I've seen the posts above. There is some good and some misleading information there.

He's the deal.
1) Even if you have regular predictable menses you can get pregnant by having sex during menstruation. Sperm live up to 6 days (not weeks) after intercourse.

2) You typically ovulate 14 days PRIOR to your next menses. How soon a woman ovulates after her period starts is quite variable. For example: if you have a 35 day cycle you typically ovulate on about day 19. If you have a 28 day cycle you typically ovulate around day 14. SO.... if you have sex within 6 days of expected ovulation your chances of pregnancy go higher.

3) The safest time to have sex to avoid pregnancy is AFTER ovulation has occured. Having sex on the day of ovulation or the day prior, gives you about a 25% chance of getting pregnant that month. If you have intercourse after ovulation, the chance of pregnancy is 0.3% (less than 1%).

To be sure you've ovulated, you could follow your basal body temperature with a special thermometer available at the drug store. Your temperature rises 1-3 days after ovulation. Once your temperature rises, it is safe to have intercourse. In future months, you can have sex until about 6 days prior to your next expected ovulation. (Until 9 days before your typical temperature rise -- to be safe.)

It is possible. I have a friend who got preggers with her first child. SHe had unprotected sex the last day of her mentration cycle.(day 5) and 3 weeks later she was preggers. She thought she was safe becaues the AVERAGE woman ovulates on day 14 but she found out later she ovulates day 7 and I ovulates day 19 on a 28-21 day cycle. THe 14 day rule does not always apply to every woman

Yes it is possible to get pregnant while on your period but it's unlikely. Most females ovulate about 14 days after the start of their period however some females with irregular cycles can ovulate at anytime during their cycle. So yes it is possible.

You're most fertile time is from 10 to 15 days after you start your period. However it is very posible to get pregnant at other times of the month...and yes even when you are having your peiod although it is a lower percentage.

Quite honestly if you can, it never happened to me. My bf at the time, now my hubby, used to do it carelessly when I was on my period, every month, and I never got pregnant. I think that's the only time of the month you can't get pregnant. You would best benefit from asking your dr. this question though, just to make sure.

Usually not, because your period is the discarding of an unfertilized egg, that because it was not fertilized is dead. Now some cases and women have become pregnant during their period, but I do believe it is really a slim chance.

Well they say that right after your period you can pregnant but I would say wear a condom anyway. Because it is better to be safe than sorry. Also condoms don't really stop you from getting prgnant so I would say dont have sex at all. It really would help you. But you dont have to take my advise do what you please.

No honey you cant you can only get pregnant when you ovulate. this is usually 14 days after the first day of your period, having intercourse during your period is probably the most safe time. x

yes.
The menstrual cycle is the female reproductive cycle that makes eggs available for fertilization. Menstruation involves the hypothalamus, pituitary and ovary, and in humans lasts roughly 28 days (this can vary greatly between individuals).
The menstrual cycle can be divided into approximately two halves:
· the follicular phase. In the follicular phase, the biochemical and physiological events (secretions of LH, FSH and estrogen) support the growth of the follicle (the cell complex that surrounds and nurtures the egg) in the ovary and build up the lining of the uterus to receive a fertilized egg. At mid-cycle, when the egg is ready, a chemical signal -- a surge of LH and FSH -- tells the ovary to release the egg. This stage is called ovulation, and is the optimum time for fertilization to take place.
· the luteal phase. In the luteal phase, the remnants of the follicle (corpus luteum) keep secreting estrogen and progesterone to maintain the readiness of the uterus. If the egg is fertilized, then the luteal phase continues throughout pregnancy. If the egg is not fertilized, then the corpus luteum dies, the uterus sheds its lining, menses begins and another menstrual cycle ensues.
Here is a very detailed look at the events that occur during the menstrual cycle:
· Menses (approx. Day 0 to 5)
Typically, the menstrual cycle begins with the onset of menses, bleeding and loss of the tissue lining of the uterus, which lasts from 5 to 7 days (variable among women). During menses:
§ The levels of estrogen and progesterone in the blood from the previous cycle begin to drop to their lowest levels.
§ Small episodic pulses of GnRH from the hypothalamus lead to small pulses of LH and FSH from the pituitary. LH and FSH stimulate several follicles (each containing an egg cell) to develop in the ovaries.
§ The follicles secrete estrogen. The follicle that develops first (dominant follicle) secretes greater amounts of estrogen than the others, and this hormones suppresses the development of the other follicles. The dominant follicle develops outer layers of cells, called granulosa cells, and a fluid-filled space called the antrum. It also continues to secrete estrogen.
· Follicular Phase: Part I (approx. Day 6 to 10)
§ The primary follicle continues to develop and grow larger. The antrum gets bigger, and pressure develops inside the follicle. The follicle secretes estrogen at a faster rate.
§ Estrogen levels in the blood rise. The rising estrogen levels will eventually signal the brain that the egg is ready to be released.
§ The rising estrogen levels stimulate growth in the tissue and blood vessels that line the uterus. The uterus lining gets thicker in preparation to receive a fertilized egg.
§ LH and FSH levels remain low but steady, supporting the development of the follicle.
· Follicular Phase: Part II (approx. Day 11 to 14 )
§ The primary follicle continues to develop, grow larger and is about ready to be released. The antrum grows, and pressure is near its highest level inside the follicle. The follicle continues to secrete estrogen at a faster rate.
§ Estrogen levels are at their highest, signaling that the egg is ready to be released.
§ LH and FSH levels remain low but steady, supporting the development of the follicle.
· The uterine lining continues to grow in response to stimulation by estrogen. The mucus plug in the cervix becomes thin and watery. Ovulation (approx. Day 15)
The high estrogen levels have signaled the brain that it is time to ovulate.
§ The hypothalamus secretes massive amounts of GnRH, stimulating the anterior pituitary to secrete massive amounts of LH and FSH (mid-cycle LH/FSH peak). This surge lasts only 24 hours.
§ The LH and FSH stimulate enzymes in the follicle. The enzymatic reactions, along with the pressure of the antrum, release the egg from the follicle. The egg travels into the Fallopian tube, where fertilization can take place. The egg can survive for about 12 to 24 hours after ovulation. The remainder of the follicle, the corpus luteum, stays in the ovary. The corpus luteum secretes estrogen and progesterone.
§ The lining of the uterus approaches its thickest and is ready to receive a fertilized egg.
§ The cervical mucus is at its thinnest.
This is the optimum time for fertilization to occur.
· Luteal Phase (approx. Day 16 to 28)
The corpus luteum degenerates.
§ The egg gets swept along by gradual wave-like motions of the finger-like projections in the walls of the Fallopian tube.
§ LH and FSH levels fall back to their low, steady levels.
§ Estrogen levels fall somewhat after the LH/FSH surge, but rebound due to continued secretion of estrogen and progesterone by the corpus luteum.
§ The uterine lining remains thick and ready to host a fertilized egg or growing embryo.
§ The corpus luteum shrinks and begins to die. It is programmed to die in 14 days unless it receives stimulation from human chorionic gonadotropin (hCG), a hormone secreted from a growing embryo.
o If fertilization occurs, and the embryo implants in the lining of the uterus, hCG rescues the corpus luteum and it continues to secrete estrogen and progesterone throughout the pregnancy.
o If fertilization does not occur, the corpus luteum dies at the end of the luteal phase. The unfertilized egg also dies and passes out of the uterus when menses begins. Estrogen and progesterone levels fall, menses starts and the uterine lining is shed. A new cycle begins.
