Pms? Or pregnant?

Hi I just turned 16 so if I’m pregnant I’m gonna freak out. I had sex 16 days ago, we used a condom and he never came. The condom never broke or anything (I checked with water). I ovualted 3-4 days later. I start my period is about 6 days and I have symptoms. I have :

Cramps on my right and left side, it switches off.

I think I have heartburn or something because my chest really hurts, and then I can feel it in my stomach.

Moody (crying and angry)

Those are all I really have. When I stand up I’m dizzy but I think that’s because of the heat. I can’t get a test for probably another 2 weeks. Can someone please give me advice. I’m so scared

- also I never get heartburn
