I'm going insane.

Ok, so I've been having unprotected sex for 2 months now. About a week ago I started getting little symptoms like brownish discharge and cramping. Recently they've become like... horrible. I can't sleep at night because I'm CONSTANTLY going to the bathroom. I feel nauseas a lot, My abdomen just feel weird and I normally sleep on my stomach but I can't now because its so uncomfortable. Another major problem is burping constantly and its starting to annoy my parents. I thought maybe I was having some sort of problems with major gas so I bought something for it but its not going away. I'm still bloated and have bad gas. The main thing that got me worried about pregnancy is headaches, I never had them before. Now I can't go a day without taking something for a headache. I know all this can't be in my head.

I took a pregnancy test like 2 or 3 days ago and it came back neg. I don't understand how I can have all these symptoms and have a neg. test. And I'm seriously like frustrated and going crazy here because if it isn't pregnancy then I have no idea whats wrong with me.

The End.
