Hello, I had an elective abortion at 13 weeks Sept. 29th. On Oct. 9th I had protective sex. On Oct. 26th my primary care Dr took blood to test for diseases ect. She had told me my HCG said I was still pregnant. I had my 4 week check up with the clinic who preformed the abortion yesterday Nov. 2, they did a pee test and that was negative. They did an ultrasound to make sure it was successful but they seen a mass. They said they couldn't tell me if it was a baby or not. they didn't know. They said it was measuring 5 weeks and few days... well i went back to my primary care Dr today Nov. 3rd and asked what my HCG levels were on Oct 26th and they were only at 38. She drew more blood today but I won't be getting the results until tomorrow... She even said my HCG was too low for being 4 weeks that week if i was measuring 5 weeks yesterday. She thinks it could be polyps or cyst? Is HCG at 38 normal for 4 weeks after the abortion? Or could i very well be pregnant again?
