Rising Hcg Levels after miscarriage

[mommyofone1983]

On 4/15 I was seen by my OB, he was following up on my pelvic pain I was 5 wks  4 days pregnant. He drew blood and my HCG level was 69 he told me I would miscarry and the next day (4/16) I started bleeding and passing clots. I follows up with the doctor on 4/17 and my levels were 38. I continued to bleed an pass clots until 4/20. I had sex on the 4/20 and we did not use protection I was not trying to get pregnant but I was told that after the bleeding stops you can have sex. I went to get my HCG levels checked 4/28 and my levels were 87. I know that 87 would be a level that is normal for 3 to 4wks pregnant. I had sex 8 days before I had the levels checked I don't think I am pregnant but I am also confused about how my levels were so low and the bleeding stopped and now they are 87. What could be the problem?  My doctor wants to give me a pill that will cause my body to expel whatever is left but he wants to rule out possible pregnancy even though he says it is unlikely.
