I hope this helps you! I do know that when I had the sore bbs and upset tummy for about 2 weeks, I took a test and it was negative. Of course, I have had sex with my boyfriend all the time. So who knew when it happened. But I took a test the day after my turned 3 and it was neg. A few weeks later, took another and it was pos. But my symptoms left and never came back. I am thankful this pregnancy is nothing compared to my son.
Question
how long after sex can a woman become pregnant---hours, days, weeks? How would the woman know if she is pregnant? Does a woman's stomach naturally hurt directly after sex if she is pregnant?
Answer
if a couple has sex around the time that the woman produces an egg (ovulation), the male reproductive cells, or sperm, can reach the female egg and fertilise it about 5-10 minutes after the man ejaculates. If it is not quite ovulation time, but getting close to it, the sperm can travel up into the vagina and live in the small glands near the entrance of the uterus or in the fallopian tubes for to 5-6 days. The egg itself lives for less than 24 hours after it is ovulated so sperm have to fertilise it during this time for a pregnancy to occur.
After it is fertilised the egg takes abbut 5-7 days to travel down the woman's fallopian tube to the uterus and embed itself in the lining to start a pregnancy.
The first sign most women get that they could be pregnant is that her period doesn't come at the expected time or is much lighter than usual. It's best to wait a couple of days after a period is due to do a pregnancy test,because by then there is enough pregnancy hormone in the urine for the test to be reliable. You can buy a pregnancy test that you do yourself at home from a supermarket or chemist, or you can see your doctor who will do the test on the spot, or send off a blood test if there is any doubt about the result. Some, but not all, women will get other symptoms which let them know they are pregnant-symptoms such as tiredness, nausea, breast tenderness or passing urine more often. These symptoms usually start about a week after the period is missed.
While many women find they get some mild lower abdominal discomfort during early prenancy as the uterus grows and stretches the surrounding support structures, more severe pain could be the first sign of an ectopic pregnancy (where the pregnancy grows outside the uterus), a possible early miscarriage, an ovarian cyst or even an infection. So any pain a woman experiences when pregnant, whether this happens during sex or not, should really be discussed with her doctor so that early treatment can be arranged if needed.
