Peeps answered Friday May 9 2008, 3:37 pm: A woman ovulates, roughly, 14 or 15 days from the beginning of her last period; however, if your period is not a perfectly exact 28 day cycle then this can be thrown off. Ovulation lasts a few days. Your body's temperature slightly changes during this time and you secrete more cervical mucus to ensure there is enough for sperm to travel in properly. During this time sperm that entire your body are able to live slightly longer than usual. Sperm typically can live in a woman's body for 5 - 7days, though it is not unheard of to find a few still alive at the two week mark.
It only takes ONE sperm to fertilize your one egg. Sperm are well equipped to find their way to their goal and they will do anything to ensure fertilization. A man's pre-ejaculatory fluid can be hard to distinguish after engaging in unprotected sexual intercourse because it is a smaller quantity and is thinner. Yes, it is likely it contacts sperm that can still impregnate you just the same.
Also, ovulation is actually when you are at your peak fertility zone. Basically, you are equally fertile every day of your cycle, including the days you are on your period. The only time you are more fertile than usual is when you are ovulating (when the egg has been released from the ovary and begins traveling down the fallopian tubes). So, this means you can get pregnant during ANY day of your regular cycle equally and you have more chance of becoming pregnant during ovulation.
Ovulation tends to last a couple of days. Usually sometime during this travel is when the egg becomes fertilized and it attaches to your uterine wall when it reaches your uterus. Sometimes the egg is fertilized in the uterus; sometimes the egg is fertilized in the fallopian tube way too early and a baby begins to grown in the tube (which can cause MAJOR issues and can be very dangerous).
It can be difficult to tell if you're ovulating or not if you're not keeping a very close track on your daily discharge and internal temperature. Many things can also throw off your regular ovulation cycle such as: stress, hormonal birth control, antibiotics, and major diet changes.
Hormonal birth control is to make you stop ovulating actually. It tricks your body into thinking it has already released an egg. Of course, sometimes the body doesn't really care and releases another one anyway (yes, it happens fairly often, believe it or not) so birth control pills are not 100% effective on preventing pregnancy (or STD/STI transmission). I would most definately continue using condoms if I were to engage in sexual intercourse since no form of birth control is 100% effective.
I hope I've helped you out in understanding how your body works. If you have any other questions regarding this matter feel free to ask me :) [ Peeps's advice column | Ask Peeps A Question ]
