I'm 18, about to turn 19 years old in a few days and I've been with my boyfriend for almost 3 years.

We had sex about a month ago using a condom and it broke. We didn't even realize it until after he went inside me. As stupid as we were thinking, we ran out of condoms, so every time after that, he just pulled out.

I started to bleed about a week- week and a half early. I don't know if it was implantation bleeding or my actual period because it was different. It was just like a light period, but it kept starting and stopping.

I've been having diarrhea for the past few days and I've also been getting some headaches. I have no idea if they could be symptoms, because I heard they were and also I heard they weren't.

I don't know if it's possible, but I swear my stomach is getting bigger.

ANY ADVICE OR IDEAS!?
