Having Sex 18 Hours Before Ovulation

Mandy asks…

If I have sex 11 days after my ovulation and 2 days before my projected period, what are my pregnancy chances?

I am 17 turning 18 in two months, and my boyfriend has been the only guy that I’ve ever been with romantically.

I have a regular menstrual cycle of 28 days and I’ve already ovulated this past week on the 2nd of April and my projected period date will be on the 15th of April. We’re planning to have sex without a condom. He tells me that he wants to ejaculate inside me. (if you’re wondering about STD and such, we both had been virgins when we first had sex) so I want to know my chances of a pregnancy because I want to avoid it if possible. If there is a 30% chance of getting pregnant, we will use a condom. I know that sperm approx. last about 5 days in the vagina and the chances of me getting pregnant 11 days after ovulating is quite slim because the egg can live no longer than 24-48 hours after ovulating. So if I have unprotected sex on the 13th, I will have 10 days including my period until I hit my projected fertile ovulation days. Every time that I’ve ovulated, I’ve always had really bad cramping called Mittelschermz. This is a pain that coincides with ovulation. Also, I have no way of getting pills without problems with family members.

Please be courteous of your answers.

Thank you

If there’s a 30% chance of pregnancy, you’ll use a condom? Wow.

Percentages are crap. The chance of pregnancy during the fertility window are only 25%, and you certainly don’t take any chances then, do you? Because a 1 in 4 chance is too high, if you don’t want to be pregnant. If I said there was maybe a five-percent chance at the end of your cycle, that’s still 1 in 20, and I don’t know why you’d risk that just to indulge your boyfriend (who really needs to cool his jets). If you manage to get pregnant, you’ll be the one who’s 100% pregnant.

Those ovulation cramps are a handy thing to have, but they’re not a guarantee.

What are my chances of getting pregnant?

Okay here we go my husband and i are ttc.we actually did but i unfortunately had a miscarriage on July 4th. i spoke to my doctor and she said just to wait for a complete cycle before we tried again.Well i had my perion on May 23rd i miscarried on July 4th i had my period on August 7 so they tell me that my ovulation should have been on or beetween the 20 to 22 we had the humpty dance on the 13th,18th,19th and 23rd. are there any chances that i could get pregnant since ive heard that sperm can live about 5 days and if i had sex a day after my ovulation date?? thanks :)

Pregnancy Advisor’s answers:

Yes you could get pregnant, even the day after you ovulate as your eggs can survive up to 12-24 hours after you ovulate before conception. Of course, that being said, there is no guarantee that you ovulated on the 20-22 as the 14 day mark is just that, a mark right in the middle of your cycles. Some women don’t ovulate till later than that and some sooner. For me, I averaged 17 to 19 day ovulation times. So, unless you are temping and/or using ovulation kits there is no way to determine whether or not your ovulating days are correct.

What’s the latest any of you have been for your period after taking Plan B?

From what I understand, most people start their period about a week or two after taking Plan B. But apparently after that, your period can be late or early if I’m not mistaken. I’m really just curious more than anything as to what “a high dose of hormones” really does to your menstrual cycle. I’ve been to the Plan B site, so I have seen statistics – I’m wondering about personal experience with the Plan B pill. What is the longest amount of time (or shortest) any of you have waited to, um, re-start?

Pregnancy Advisor’s answers:

Here’s some very good info on the Plan B pill,
read and decide for yourself.


Plan B Particulars: The Facts You Need to Know
Author: Karen Barrow
Medically Reviewed On: September 01, 2006

The Food and Drug Administration has decided that women over the age of 18 will not need a prescription to purchase Plan B, a form of emergency contraception, while younger girls will need permission from a doctor. Unlike other forms of contraception, this drug allows women to lower their risk of getting pregnant after they engage in unprotected sex.

Putting aside your political stance or whatever ethical or moral qualms you have about either side of the argument, it is important to understand how Plan B works. Here are the facts:

What is Emergency Contraception?
Emergency contraception, sometimes called emergency birth control, is used to prevent a women who has had unprotected sex from becoming pregnant. It is not meant to be used routinely, but only in particular instances, such as when:

* Birth control is forgotten entirely
* A condom breaks or comes off
* A woman forgets to take two or more birth control pills in a row
* A woman is late in getting a birth control injection
* A woman is forced to have unprotected sex

It is important to realize that, like the birth control pill, patch and injections, emergency contraception does not protect against sexually transmitted diseases, such as HIV, herpes and chlamydia.

Also emergency contraception only works before a woman becomes pregnant. In other words, it must be taken before the egg is fertilized for it to be effective.

What is Plan B?
Plan B is a type of emergency contraception approved by the FDA. It is prescribed as a packet of two pills containing synthetic progestin, a type of hormone naturally made in a woman’s body.

The drug works in the same way as a typical birth control pill in that it prevents the release of an egg from the ovary so fertilization cannot happen. If ovulation has already occurred, Plan B can also prevent the sperm from fertilizing the egg.

Plan B is ineffective, however, once fertilization happens and the egg is implanted into the woman’s uterus. That’s why the first Plan B pill must be taken within the first 72 hours after having unprotected sex. The sooner Plan B is taken after intercourse, the more effective it is. Twelve hours later, a second pill is taken. According to the manufacturer’s website, “When you take Plan B as directed, you reduce your risk for pregnancy by up to 89 percent.”

Is Plan B the Same as the Abortion Pill?
No. You may have heard Plan B called the “morning after pill”, but it is significantly different than the abortion pill, RU-486. That drug is used to end an existing pregnancy by causing the uterus to force out the fertilized egg. Plan B only prevents a pregnancy, it cannot end a pregnancy. And it shouldn’t be taken by pregnant women for that purpose.

However, if the drug is taken after fertilization of the egg, there is no evidence that Plan B will in any way effect the pregnancy.

Are There any Risks of Taking Plan B?
The most common side effects of Plan B impact menstruation, causing early or late periods and lighter or heavier menstrual bleeding. Nausea, abdominal pain, dizziness and breast tenderness may also occur.

If you vomit after taking Plan B, the National Women’s Health Information Center advises you to call a doctor for advice.

Also, there is still the risk that you may become pregnant even after taking Plan B. So, if you do not begin menstruation in three weeks, or have other symptoms of pregnancy, consider taking a pregnancy test or seeing a doctor.

Better to have sex every day or every other day when ttc?

Im ttc and my and my fertile days start Friday and I ovulate next Wed, but I want to know if is better to have sex every other day or every day. I heard that both ways is good, has anyone tried both and what work better and faster to get pregnant.

Pregnancy Advisor’s answers:

Daily unprotected sex has better chances (Compared with alternate days).
However, do not miss the day of ovulation. Please determine your ovulation by using Ovulation Test kits. DO NOT RELY ON THE CALENDER or COMPUTER Methods.
Additional tips follows:
1. Determine your day of ovulation using Ovulation Test Kits. In Ladies with REGULAR CYCLE You need to test from the 10th to 18th day of your cycle. (First day of bleeding is the First day of the cycle).
2. Unprotected sex on the day or on the eve or one day after ovulation will yield good result. So calm down and get yourself composed. Any form of STRESS will get you away from your goal.
- Plan a vacation, far away from the madding crowd, coinciding with your ovulation period. Suggest natural water fall or mountainous resort.
3. Get your hubby’s seminal fluid examined by a reputable laboratory. Your hubby needs three days of sexual absenteeism (including masturbation) for the test. Since spermatozoa are easily perishable outside the reproductive system, your hubby has to go the laboratory, masturbate and ejaculate into the sterile container and hand over then and there, for the examination.

- Plus some fine tips below, to follow:
i. Determine your ovulation day, using the Ovulation kit.
Ii. Coincide unprotected sex to the Ovulation (Eve / on the very day of ovulation / the very following day after ovulation ). Ovum released can survive only for 24 hours.
Iii. Plenty of love making / foreplay prior to the actual act, because that will well lubricate your reproductive tract and remove the Vaginal acidity. Vaginal acidity can destroy the spermatozoa.
Iv. Elevate your Pelvis, with a pillow, at least prior to ejaculation. . Missionary position with your legs on your hubby’s shoulder. This will provide a deep penetration and deposition of semen deep inside the vagina, almost at the lips of the cervix and to ensure the smooth flowing of semen into the cervix, uterus and fallopian tubes.
V. Try to reach climax/female orgasm at the time of ejaculation, so that your cervix will literally suck in all the ejaculatory fluid. For completion sake, I had given the additional benefits of female orgasm below

a. If your orgasm is always late or your hubby is having premature ejaculation, begin the sex in Reverse missionary (with you on the top).
B.Reverse Missionary aids in two ways-
Firstly the women will attain orgasm earlier because of the stimulation of G spot
Secondly it also delays the premature ejaculation

Female Orgasm keeps the woman lying down for some time. This resting, passively retaining sperm and increasing her probability of conception. . British biologists, Robin Baker and Mark Bellis team counted sperm from over 300 instances of human copulation and found that a woman climaxes any time between a minute before to 45 minutes after her lover ejaculates, retains significantly more sperm (In non orgasmic, she hardly retain any sperm)..

Vi. Try to lie on your back for at least 4 to 5 hours after sex, so that even the slow-moving or the late comer spermatozoa too will find the way into the female reproductive system.
Vii. Strictly no washing, immediately after sex, especially on or around the day of ovulation.

Last but not the least, Sincere Prayers to the Almighty

Sandy asks…

How do I check my basal temperature?

I am trying to count my days and find out when I am fertile. Can someone please explain to me the way the “checking you basal tempurater” work. Someone has told me that I need to do this, but not sure when I have to check. Thanks

Pregnancy Advisor’s answers:

# Take your temperature first thing in the morning before you get out of bed or even speak — leave your thermometer at your bedside within easy reach so you don’t have to move much to get it. If you use a glass thermometer, make sure you shake it down before going to bed.

# Try to take the temperature at as close to the same time each day as possible — set an alarm if you need to. Staying within a half hour either side of your average time is a good idea because your temp can vary with the time (i.e., if you usually take your temperature at 6 a.m., it is OK to take your BBT between 5:30-6:30, but the closer to 6 the better). The normal variation is by up to .2 degrees per hour — lower if you take your temperature early, higher if you take it late.

# It is best to take your BBT after a minimum of 5 hours sleep, and at least 3 in a row is preferable.

# You can take your temperature orally, vaginally, or rectally — just stay with the same method for the entire cycle.

# You should try to place the thermometer the same way each day (same location of your mouth, same depth vaginally and rectally).

# Plot your temperature on your chart each day, but refrain from reading too much into it until the cycle is done.

# Some women, not all, have a temperature drop when they ovulate. If you see this drop, it is a good idea to have sex in case you are ovulating.

# What you are looking for is a temperature shift of at least .4 degrees over a 48-hour period to indicate ovulation. This shift should be above the highest temperatures in the previous six days, allowing one temperature to be thrown out as inaccurate (fluke, illness). Perhaps the best way to explain this is to show an example.
Coverline.jpg – 120843 Bytes
In the image above, the seven BBTs before ovulation are 97.2, 97.3, 97.8, 97.4, 97.2, 97.3, 97.0 then it jumps to 97.7 and then 98. Ovulation most likely occurred on the day with the 97.0 and you can comfortably draw a coverline at 97.6. You just ignore the 97.8 on day 10.

# After you see a temperature shift for at least three days, or at the end of your cycle, you can draw a coverline between your follicular phase and luteal phase temperatures. With luck, it is easy to see a clear shift and draw your line between the highest follicular phase BBT and the lowest luteal phase BBT as in the sample above. The main reason for drawing this line is just to clearly delineate that your chart is biphasic.

# Look at the chart at the end of the month to analyze what happened.

# Chart for a few months and look for patterns.

# If your temperature stays up for 18 days or more after ovulation, you should test for pregnancy.
