Well i got my period on the 12th of this month, and ended the 17. And i also had sex on the 12th right when my period came. I think i'm going to take it the 26th and then again next week.
Do you know how long your cycle is? (start of your period to the start of the next?). A typical women will have a 28 day cycle, so basically 14 days after her first period day she will ovulate and that egg is viable for 24-48 hours or so. When you have a period your body is shedding everything and getting ready for a new cycle. So basically this means it is more difficult to get pregnant if you are having sex during your period. Sperm can live inside of a women for up to 7 days if conditions are good and if you have a really short cycle, say 24 days or something then there is a slight chance you can get pregnant because you might ovulate within those 7 days that the sperm can stay alive. So basically chance are low that you are pregnant but it is not 100% that you are not. You have to wait at least two weeks and take a HPT.
lol but i don't know if i ovulate early or anything?
i would say probably not unless you ovulate very early on in your cycle... it is possible i guess if you do and the sperm survive in your system long enough to get to an egg when you do ovulate... unfortunately though its going to be a long wait until you find out if you are :)
