Helen asks…

LH surge question, please help?

Hi there me and my husband have been trying to get pregnant, i had a really light period on the 1st of sept so i started testing this week. On wed after noon i had a positive opk (my husband works out of town so we couldnt do anything) Thursday the test line was dark but not as dark as control line so it was a negative then friday morning it was darker again so a positive, friday afternoon was negative ( but my husband was home so we did the bd in case) Now this morning it is positive again. Does anyone know if this is accurate can it keep saying positive and negative every other time i test im so very confused, I have no signs of ovulation like i normally do no sore breasts and no cm, please help me, i used to different kits so i know they r accurate, please help me?

can someone give me answers please… ttc maybe pregnant/?

Me and my husband are ttc. im using the opk method to see wen i ovulate.?
in the beggining of july i was very sick. i was supposed to get my period 07/8 but i got it 07/6 it was horrible i was throwing up and wit stomach pains recently i was sick in bed sleeping all day 07/15 and my husband has had a big appetite. ive been craving weird stuff too. so now im doing the opk since 7/11 and till this day i havent had a lh surge there all negative. does this mean im pregnant? someone please help we really want a little baby in our lives. i hope this is it. thanks 4 your help

Pregnancy Advisor’s answers:

Your husbands appetite has nothing to do with it.

If you got your period on 7/6, then you are at cycle day 18. You should have had a positive OPK by now. Negative OPK does not indicate pregnancy, actually, pregnant women will get a positive on an OPK because the hormones are very similar, you can read about that here: www.peeonastick.com

If you want to know whether you are ovulating, start charting your temps. Go to www.fertilityfriend.com or www.tcoyf.com to learn more about it.

Good luck

Sharon asks…

if you have had a positive opk for one day and then the next day a negative could you be pregnant?

i’m going to a fertility dr. and he did a water ultrasound and saw a egg sack in my left ovary and said to ” u know” every other day and i was also using an opk test and it came up positived one day then the next day it showed up negitive plus the day before it show positive it was negitive so could i be pregnant and thats why it show up negitive after the postive test
ok not to sure how the question was confusing. but i’ve been going to a feritly dr. and he did a water utrasound and saw a egg sack in my left ovary and told me to start having sex everyother day. well i brought one of the opk test kits and started using them i had a negitive one day a positive the next day and the day after i had a negitive. well i know that i ovalutived cause the dr told me i was about to. so i’m just confused on the fact i had a negitive positive and then a negitive. so could i still be pregnant

Pregnancy Advisor’s answers:

Surely it just means you had your LH Surge on the day you tested. I had a positive test on Saturday, it was negative Friday and yesterday, but I know that I have ovulated as I have had some bad abdo pains which are still there! Im not sure if you can get a false positive.

Mary asks…

What regulates the production of GnRH, LH, and FSH?

Pregnancy Advisor’s answers:

It is difficult to explain these hormones without explaining the other events occuring simultaneously. So first, I will explain these other events. And then I shall indicate what happens to the hormones. And Lastly, I shall conclude what regulates GnRH, LH and FSH.

GnRH, LH, and FSH secretion is regulated in a monthly Ovarian cycle.

1. In the beginning, there is low estrogen and progesterone circulating in the body–> this will trigger the hypothalamus to secrete GnRH–> GnRH will act on the anterior pituitary to produce LH and FSH
2. LH and FSH levels gradually increase
3. When threshold is reached, an LH surge (peak LH production) occurs. This also happens for FSH but it is smaller and is overshadowed by the LH surge
4. This LH surge will trigger the developing ovum (at the stage of primordial follicle) to burst. This burst is called ovulation, which happens around the 14th day after the 1st day of menstruation.
5. When the primordial follicle bursts, the actual egg cell is released and the cells that once contained it will morph into another form called the corpus luteum, in a process called luteinization. Let’s leave the events of the released ovum for another topic. Let’s discuss the corpus luteum.
6. The corpus luteum produces estrogen and progesterone. Apart from the corpus luteum, the only tissue of the body capable of producing progesterone and estrogen is the adrenal gland, but in such minute amounts as compared to the C. Luteum.**
7. If the released egg is fertilized, the corpus luteum will continue secreting prog. And estro. However, if the egg is not, then it will degenerate.
8. Without the c. Luteum, prog. And estro. Levels fall back. The cycle is nearing its end, it will be after several days when a group of ova would be recruited to repeat the cycle.

As for HORMONAL levels, these are what happens during the previous #1-8 events:
1. Low Estrogen and progesterone–>stimulates release of GnRH from hypothalamus–>stimulates release of FSH and LH from ant. Pituitary
2. Increasing FSH and LH levels
3-4. Max. LH and FSH levels
5-6. Gradually decreasing LH and FSH levels; gradually increasing progesterone and estrogen levels
7. High estrogen and progesterone levels (non-pregnant)
8. Decreasing estrogen and progesterone

And that is the summary of follicular and hormonal events. On to your question…

1. As you noticed, GnRH, LH and FSH are primarily regulated by HORMONAL mechanisms. The presence of one hormone stimulates the next hormone. But there are also other hormones that affect this system. For example, when LH increases, it stimulates the production of inhibin–>inhibin would act to decrease FSH secretion.
2. FEEDBACK mechanisms also occur. When the hormone they are stimulating decreases, it would stimulate their production even more in a positive feedback mechanism (eg, low estrogen–> stimulates increased GnRH). In a negative feedback, if estrogen levels are high, GnRH secretion decreases. Take note of this as this dictates the ovarian cycle.
3. NEURAL mechanisms. The arcuate nucleus regulates the hourly pulsatile secretion of GnRH. Inhibitory GABA in the hypothalamus regulates the monthly LH surge.
4. Other chemical messengers also affect these hormones, like steroids. Estrogen and progesterone are actually steroids so if take in steroids, GnRH secretion can decrease in a negative feedback mechanism.

Whew. There, I hope that I had answered your question well.=)

**This is the basis of menopause. When the ovum pool is depleted, the sole source of estrogen is the adrenal gland.

Negative OPK and HPT, what do you think?

Hi, I know if you are pregnant an Ovulation Predictor Test will show positive as it recognises the pregnancy hormone aswell as LH. http://www.peeonastick.com/opkhpt.html

But could you still be pregnant if a OPK shows negative? Also negative HPT, but 13 days late?

Opinions and experience please.

When did you get your BFP? How far along were you?

Thanks for reading and baby dust to everyone trying :)

Pregnancy Advisor’s answers:

If you are 13 days late, a HPT would almost definitely be positive. So you should see your doctor for a blood test to detect whether or not you are pregnant. If you are not, you can ask your doctor about your absent period.

A pregnancy test can be positive no earlier than 14 days after ovulation. However, it is only 99% accurate when your period is due/late. Before then, even tests that claim to detect pregnancy before your period is due, are only 50-60% accurate at that stage.

Yes, you could be pregnant if the OPK is negative. The OPK detects the LH surge, which occurs before and during ovulation. The OPK is not a pregnancy test.

LH and HCG are molecularlly almost identical, which is why OPKs can detect pregnancy – but much later than a standard HPT. And because they are designed to detect LH, they are much less reliable. Otherwise, what’s the point of HPTs? They’d be extinct if OPKs worked just as well.
