Okay, so I started birth control exactly two months ago, and about a week ago me and my boyfriend had sex without a condom a couple of times. He didn't ejaculate inside of me any of the times and peed before we had sex almost every time except for maybe once. I'm really scared I'm pregnant because I'm having cramps and I was supposed to get my period yesterday but I haven't gotten it. I also have a weird cycle because of the bc, I have two periods. A really small one, which should've started yesterday, and also a more heavy one that should start on September 15th. My last period started August 19th and ended the 24th. Help??
Oh and also I had only a small amount of this weird light brown stuff and a little red ball looking thing inside my underwear? what could that have been?
