hi, I had unprotected sex during my period and he didn't come inside me as far as I know. Its been exactly 10 weeks and I'm feeling tired and sleepy all the time. two weeks ago I was having trouble sleeping now I can't seem to get enough. I'm also having some very slight nausea that goes away sometimes. I've had my period twice since and it has been shorter and lighter than normal. The first lasted 4 days and the second lasted only 3 days. Though feeling silly asking, is there a possibility that I could be pregnant?
