I have gotten blood work all came back negatives and the doctors are sending me for an ultrasound, I haven't had a period since December 10th and I have nearly every symptom! I just feel like my body is trying to tell me something. I don't feel right and I'm just not acting myself and others are noticing. I am really up and down I am constantly going from being crying to yelling because either someone or my boyfriend didn't say something right. I an constantly dead I can't seem to get enough sleep no matter how early I go to bed. an constantly dead I can't seem to get enough sleep no matter how early I go to bed. All I want to eat is ice cream and Tim bits, and I used to have a high sex drive but lately I am so tired that I couldn't do it. And my boobs and legs are getting vainly and have stretch marks and now my nipples are mainly hard even when it's not cold and I'm not aroused and they are darkening. I bloat my belly looks bigger at certain times of the day.  I had spotting 8 days after my boyfriend finished inside me. Usually I cramp for an hour and bleed heavily . But instead I cramped for 2 days and had discharge and a little few dots of blood when whipping. Okay so here's some background information: 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
