Yes. It isn't common, but it does occur. The reason some women conceive when they are on their periods is because they either have a short cycle or they just ovulate early and have a long luteal phase. You can have sex up to 7 days before ovulation and conceive becasue the sperm can live that long. Sperm life inside the woman's body is generally 3 to 4 days, but they CAN survive for up to 7 days. This means you have a fertile window of UP TO 7 days. So, lets say your period is 7 days long and your cycle is 26 days long. You have sex on day 6 of your cycle - you are still bleeding. Now lets say you ovulate on day 11. This will make your luteal phase 15 days, which is very average. You had sex 5 days before you ovulate so there COULD still be viable sperm waiting to fertilize the egg.

It is unlikely, but possible, to conceive during your period. Sperm can live inside the female reproductive system for up to five days, so if you have a shorter menstrual cycle and ovulate early, there is a small chance of conception. It is always best to use protection to prevent unwanted pregnancy.
