I didn't know I was pregnent, on Oct 13th, just thought Iwas havin a bad period,( heavy, cramping, clotting). it lasted the same number of days as my period. Then one month later, ddn't have y period, but knew Icouldn't be pregent,( no sex). Took at test Nov. 16th after being late, and it was postive. went to gyn, and got blood work, they said i was pregent. I argued with the nurse, saying it couldn't be true. My hcg levels that day were 3100, so 2 days later went back and the levels were down to 2000, so signs I had a miscarriage. So they are keeping aneye on my levels to zero. Then 2 days later started bleeding and cramping again. Is this a sign that it is an incomplete miscarriage? What should I do?
