I had unprotected sex on the 10th, my period ended on the 7th. It feels as if I'm going to get my period but I'm not due till the 3/3 I've been having headaches, cramping, back pain, fatigue ( I usually sleep about 6hrs now I'm sleeping like 11hrs) is it possible I'm pregnant?
With a regular period you will ovualate around two weeks(14 days) after the first day of your period. If you started your period on the first then having sexual intercourse on the 10th that was unprotected could cause you to conceive. Sperm can live inside you up to three days. A pregnancy test will not read your pregnant until after your missed period. I would wait until you miss your period and then take a pregnancy test.
