Well I start my period at the end and beginning of a month and I started late. Me and my fiancŽe had sex 2 weeks before and it was from the back. The next week I was feeling sick and I started going to bed 3 hours earlier.. also lower stomach pain. Could I be pregnant? I am considering taking birth control but I don't want to.. if I am pregnant.. and something bad happen. I've tried asking someone but they all say the same thing: take a pregnancy test.

The advice you got from the others you asked is absolutely correct. Take a pregnancy test. The possibility certainly exists that you could be pregnant, but we can't tell you online if that is the case. Make sure to use first morning urine with an HPT.
