Am I pregnant?

I've been dating my boyfriend for about 7-8 months now and we've been having a physical relationship for about 9. A week and a half or two weeks ago I began getting concerned. I was late, I was also feeling weird. So I googled about it. I had all but one major symptom. I didn't have heart burn. But as soon as my worry peaked I began my period. I was so thankful, but it wasn't like most of my periods. Then now after it's over I spotted for a few days after and I am still feeling poor. I haven't been eating much, but I've had huge cravings for doughnuts. I bought my third dozen since like Thursday and ate 6 today right after purchasing them and arriving to work. (I work across the street from the store I bought them at) I've also noticed my butt is getting larger and I'm getting hippy. And on top of it all I've been feeling queezy and been horny as a bull. We don't really use condoms but I'm on birth control pills. He's never came in me and don't be too judgmental but to be honest I completely understand if you do that I'm 17 and a junior in high school. Thank y'all. I really appreciate your help positive and negative.
