Hi, I'm 20 years old, and me and my boyfriend are very sexually active. Almost twice or even more than a week. 

I got my last period this February 16, and its April 17 now and I havent got my period.

We had sex on his birthday, and he told me that "Im sorry, I cant control it" but he cum outside. It's playing on my mind right now. 

Since the first time of me having a period, I am a year delayed (im 11 or 12) . And figured out that I'm irregular. 

It seems that I dont have any sign of pregnancy, and took 2 PTs and its NEGATIVE. 

But I noticed that my tummy is bigger than before. That's why I'm stressed out, if I'm pregnant or am I just getting fat. I dont know what to do. I'm getting paranoid, me and my boyfriend.
