My last period was on Jan 6th, and I ovulated on the 25th and next period isnt til Feb 3rd., I had sex without protection on the 20-23, and I started sleeping, and I have been for 6 days, it was a light pink, and than went to a light brown. I took a pregnancy test when I started bleeding and it said negative. I think im going to wait til starting day to take another test. But, when I sleep, i usually sleep on my stomach, and lately my stomach has felt weird when sleeping on it, and I can sleep in now, i never could before, and .. I have crying spells over things that arent even that sad.. .. could I be pregnant ?
