December 29th I had unprotected sex my boyfriend finished inside of me, my birth control was messed up because of time distance, I was expecting my period on January 7-9. I took a test the day I was suppose to get my period and it came back negative. Then I took another in the evening a week later and that came back negative. On the 7 I got cramps and brown discharge on the 8th I got a little bit of light Bleeding, then nearly 1 1/2 or so after that I started experiancing food cravings, cramps and head aches. I started getting sticky white discharge.Now on the 3-5 of February I was suppose to have my next period and I got cramps and light pink/red blood and I've been nausea and very moody(one minute I'll be happy then I'm telling then I'm crying) my body doesn't feel how it usually does. I just feel sick and really hungry. My friends mom had all my symptoms and she had negative tests. Has anyone had this before? What should I do? My boyfriend says I'm just not myself. I had unprotected sex for 16 days straight in December, usually I cramp for 1 hour before I bleed heavily but the last two months it's been for days after days, and finally usually I am very heavy but these two months I can't even wear a small tampon because it is so light. Like I've been and cold flashes. I have been sweating uncontrollably I have to take my shirt off to wear sweater because I sweat so much that my shirt is too wet. I have been finding white sticky discharge. Every so often I laugh and I leak out which I didn't know that was a symptom. I fart constantly and I can't control it. My breast are itchy and they have stretch marks all of a sudden. I crave ice cream everyday. And I feel like I could be sick eating salads when I have been eating them daily for a long time. I got a blood test don't a few days ago and it was negative. I started having light cramps then brown discharge and black clumps, 2 days ago. I went to the Doctor again and they decided to do another blood test(they tested pregnancy, sex hormones and thyroid problems the first time) and they requested me to get an ultra sound. I know that people experience negative blood tests when they are suppose to be positive. My belly is starting to look different I'd be 11 weeks has anyone had similar experiences?
