I need help and just not to be judged

Well hi everyone, please don't judge me on this and don't be so cruel about it. I'm scared and idk what to do. I had sex the other day and lately my stomach has been hurting yesterday I was cramping and today it's worse I'm also bleeding but my period isn't due for 12 days and the pain is killing me rn. I'm going to a clinic Monday to be checked. My cousin thinks I was pregnant and had a possible miscarriage but I don't think I was pregnant. 

The other day like the ending of my fertility week so last week and what type of std makes you bleed wtfreak 

I did some internet research some things say that I'm pregnant now. Idk I'm only 17 I'm confused 

It's highly annoying how everybody feels as though all school make u take sex education my school didn't or I wouldn't ducking ask y'all think y'all know so much just off one post wanna know how I figured out what sex was? Cause I was fucking 7 getting raped every damned day don't feel bad and don't call me stupid based off of something nobody decided to tell me growing up I been from foster home to foster home so don't tell me what I should know and saying that I'm stupid because I don't and I'm not

I went to the doctor and pretty much they don't know either so I go back on Monday all test pretty much came back negative but I go back Monday and they are going to do blood test instead of urine test and I get results for my hiv and std\sti test

Well I got my results I have yeast and something called trigamonis(i spelled it all wrong sorry) I've never had either of those but my doctor told me to retake my pregnancy test when I come back
