I went on the pill about two months ago. My boyfriend an I have sex almost everyday unprotected. But lately he's just been pulling out so he does not ejaculate inside of me. I know it's still unsafe but I should get my period on the 17th this month . Except for I got it today. And it was more of a brownish color, my stomach has been sick for awhile and I'm usually overheated and pretty tired. Could I be pregnant?
