Ok on the day I got off my period (February 26th) me and my bf had sex and he came inside of me, I'm not on birth control and he wasn't wearing a condom. It's been 2 weeks now ( as of March 12th). I started having unexplainable cramps about a week after we had sex, and I've been very hateful and moody for about a week. I've also been very tired for the past week (but daylight savings just ended this past Sunday so I figured that would explain why I've been so tired.) I usually start my period around the 20th. Is it possible I could be pregnant?
