two weeks ago, I had unprotected sex. four days later, I got my period. But for the last week, I've been feeling off. Very tired (and more often..), no appetite, a little more frequent bowl movements and urination, my sense of smell is a little better (Smelling things I normally wouldn't have smelled). My Nipples are not darker, and I'm not nauseated, and my breasts aren't much more sensitive than right before my period.
My cycle is not always predictible (I.e. Not always 28 days in my cycle), but It always Always stays for 7 days. this time, it was a lot lighter than usual, and stayed 5.
Is it possible that I am pregnant, or am I just freaking myself out? I know this site is not a pregnancy test, but I want to know what the chances are before I go out and buy a pregnancy test-- Especially since it's only been two weeks...
