Lh Hormone Surge And Pregnancy

Mandy asks…

What are the stages before Ovulation and what happens after?

Can anyone tell me what happens when you get ready to ovulate and after ovulation? What occurs afterwards?

Pregnancy Advisor’s answers:

.The First Days of the Menstrual Cycle
The menstrual cycle actually begins with the first day of your period. During this time, estrogen levels in your body are extremely low. This signals your body to produce FSH. As the levels of FSH in your bloodstream rise, approximately 20 follicles inside of your ovary begin to mature. One of these follicles will begin to secrete estradiol, a type of estrogen, while the weaker follicles die off. As your period ends, your body will prepare for ovulation by creating a thicker uterine lining, appropriate for implantation. Your cervical mucus will also change, from thick and clumpy, to thin and slippery.

Ovulation
Ovulation occurs around the 14th day of your menstrual cycle. During this time, estrogen begins to rise rapidly, peaking about a day before ovulation. As your estrogen levels peak, your body will experience a surge in LH, triggering your ovaries to release an egg from its follicle. This egg will enter one of your fallopian tubes and travel towards your uterus. The leftover egg follicle gradually shrinks, becoming the corpus luteum. The corpus luteum secretes progesterone, helping to prepare your uterine lining for pregnancy.

Menstruation
If your egg is not fertilized after ovulation, your body will progress into the menstrual phase of its cycle. During this stage, the unfertilizied egg is expelled from the vagina along with the uterine lining. This is your menstrual period. Typically, menstruation lasts between three and seven days, though it can last as long as ten days. Your menstrual blood may change in color, ranging from bright red to deep brown. You may also notice some small clots in the blood. This is because your menstrual fluid is actually comprised of various cells and tissues. During menstruation, hormone levels drop, signalling the cycle to start all over again.

I googled stages of menstrual cycle. You should too.
Also read the book, taking charge of your fertility. It will educated you beyond what you ever thought you’d know.

What causes spotting during pregnancy?

Im 9 weeks and had this to happen twice last night and once this morning. It is very faint brownish/pinkish color. I havent had sex in a while so I know it isnt that. It is only when I wipe from using the bathroom. This is my first pregnancy so I am nervous and needing some advice. THANKS

Pregnancy Advisor’s answers:

I am a young physician and I think I may have some insight that may be useful.

During pregnancy, cyclic ovulation and your period do not occur because of several reasons, mostly hormonal. In order for an egg to be let down from the ovary (ovulation) you need a surge of a hormone from the hypothalamus called GnRh (gonadotropin releasing hormone). This surge causes an LH/FSH surge which causes ovulation. Bear with me it gets easier….

During pregnancy this surge does not occur because your progesterone and estrogen levels STAY elevated (during normal non-pregnancy times they go up and down). The high progesterone primes your uterus, causing a nice cushioned bed for the developing embryo (if its intra-uterine, hopefully. And not -intra-fallopian…but that’s a separate discussion).

Some times this cushiony bed of muscles/cells and glands slough off. The shedding of the uterine lining coincides with the spotting you are experiencing. So, little areas of your uterus are shedding its layers which causes spotting during pregnancy. After your mucous plus if formed, most of the spotting is from the cervix.

SUMMARY:
Pregnant——> elevated progesterone/estrogen——>thick cushioned uterine lining—->(cyclic shedding of this, monthly is called your period) but, during pregnancy only small (hopefully) micro areas, shed and this is what causes mid-term spotting!

Good luck…name him or her Jordan…after me!

Lisa asks…

If I tested positive on OPK but my temp did not rise did I ovulate?

If you test positive on an ovulation kit but your temp does not change what does that mean? And if your temp does change and go up will it stay up if your become pregnant?

Pregnancy Advisor’s answers:

An OPK just shows that you’re surging in LH (luteinizing hormone). This usually happens 24-48 hours before ovulation. Sometimes, our bodies surge, but don’t release an egg. Usually the OPK will drop off for a day or two, and then you’ll surge again, and hopefully ovulate then.

This is possible if you have a hormone imbalance (like with PCOS), but the more likely scenario is that you did ovulation, but your progesterone rises slowly. That means it takes a few days for the rise in temp to show. It’s not a big deal, unless your progesterone is low, which can cause miscarriage. If you notice a slow rise on one or two charts, that’s fine, but if you see a consistent pattern of low temps and bad rises, you should get checked out by a doctor.

If you become pregnant, your temps will stay high, because of the hormones released by pregnancy. However, some fluctuations are perfectly normal. When you get a positive pregnancy test, most women stop charting, just to stop the emotional rollercoaster.

Good luck!

Susan asks…

What hormones are responsible for producing fertile mucus, in the woman, during her fertile phase?

Pregnancy Advisor’s answers:

1. Pre-Ovulatory Hormones – Discussing Estrogen, FSH, LH and GnRH 2. Post-Ovulatory Hormones – Discussing Progesterone, hCG and Prolactin 3. Dispelling Day 14 Myth – Detailing the mechanics of ovulation.

Pre-Ovulatory Hormones – Estrogen, FSH, GnRH, LH
The female reproductive cycle is completely run by hormones. Without the hormones, conception would not occur. It’s no wonder that if any of the key hormones are out of whack then infertility is the result. Maintaining a balance of this fine tuned system of glands and hormone excretions is paramount in the act of conception. It has been said that hormones are the conductor of the body during pregnancy, that hormones run the show, so to speak. Learning about the reproductive hormones can give you a better understanding of what occurs during the cycle month and why you experience certain physical signs as each hormone peaks and drops off in production. These reproductive hormones are released mainly in the pre-ovulatory phase of the cycle, or the first half.

Estrogen

Estrogen is actually a term referring to three separate hormones – estrone, estradiol, and estriol. Because these three hormones are considered the “estrus-producing hormones” it is easier to simply say “estrogen” which refers to the “estrus” class of hormones.

Estrogen is the hormone responsible for the low basal body temperatures in the first half of the cycle. Estrogen prompts the cervix to produce the fertile quality cervical fluid. It controls the entire menstrual cycle. Estrogen levels start off low the first of the cycle and begin to climb as ovulation approaches. It’s the high levels of estrogen that prompt the production of the Luteinizing Hormone (LH).

Luteinizing Hormone (LH)

LH is produced by the pituitary gland. It is released in one surge prior to ovulation, which in fact prompts ovulation to occur. LH levels rise very slowly at the first half of the cycle. When the level of estrogen reaches a high peak it prompts the surge release of LH, known as the LH surge. It’s the LH surge that literally causes the ovary to burst forth the egg.

LH is the hormone detected in ovulation predictor kits. This surge takes place normally 24 hours to 72 hours before ovulation occurs. If infertility is a factor, a woman can have several LH surges in a cycle, thus making the use of ovulation predictor kits more complicated.

Follicle-Stimulating Hormone (FSH)

FSH is produced by the pituitary gland in the first half of the reproductive cycle. FSH is the hormone responsible for prompting the ovaries to produce mature ova or eggs – and the production of estrogen. The levels of FSH are above those of the other reproductive hormones at the beginning of the cycle. Very soon, the levels drop below the levels of the other reproductive hormones. Right before ovulation, FSH peaks, thus causing ovulation itself to happen.

Gonadotropin Releasing Hormone (GnRH)

GnRH is produced by the hypothalamus in the brain. It stimulates the pituitary gland in the production of FSH and lutenizing hormone (LH). This helps in the lead to follicle development and ovulation.

The hormones that run the pre-ovulatory phase of the menstrual cycle are estrogen (estrone, estradiol, and estriol), luteinizing hormone (LH), follicle-stimulating hormone (FSH), and gonadotropin releasing hormone (GnRH). These hormones must work in harmony to bring about ovulation, the release of the egg from the ovary.

Donna asks…

What is the termination of intrauterine pregnancy?

Pregnancy Advisor’s answers:

Dear mem
Now u can plan your pregnancy as u like and choose your date and time of pregnancy as u like with home check ovulation kit because Home-Check Instant Ovulation Test is designed to detect the surge in Luteinizing Hormone (LH). The body always makes small amounts of LH but prior to ovulation it makes far more. This test device will detect the LH surge which happens in the middle of your menstrual cycle, about 1 -1.5 days before ovulation.
