I know how you feel. I found out i was pregnant March 18,2012 and miscarried on March 23,2012. The doctor in the ER was guessing i was about 2 months. When i had the miscarriage my HCG levels were 21,a week later they were negative. My boyfriend and i had unprotected sex before i miscarried and once after. I still haven't gotten a period, but my breasts are tender,i am sleeping more than normal, im eating a lot more, and i keep having twinges in my stomach. Two HPT were negative but i am going to test again in a week or two
