The doctor told me to use protection for the first month on the Pill until the last two or three pill on the first packet that I didn't use protection and he came inside when when I had sex I was on my period and got off my period a day or two after having sex it's been a week since we had unprotected sex, I've been taking the pill but I don't always wake up the same time some times I'll wake up at 9 and others I'll wake up at 10 or 11 and take my pill. I've been having sharp pains at the top of my stomach,sides, and bottom also I've been having super bad headaches could I be pregnant?
