Fluctuating hcg

becky
So I have been having positive tests for over 2 weeks. I was told I had a miscarriage, my hcg was 17 and I had heavy bleeding for 4 days. Still with positive tests. On Thursday I saw my doctor, she said yes, miscarriage but wanted to check hcg. It was 138. So not a miscarriage but posibly ectopic. I go to ob thinking methotrexate or surgery. He sees thickening, but nothing more. So that fear is gone there. He says, possibly a spontaneous abortion if levels go down. But...i was alreafy having a miscarriage? Or, posibly a viable pregnancy. So we were hoping for higher levels...My levels went down to 66. I do another test tomorrow. But, has anyone experienced this? I started spotting this evening. Still positive tests, but faint. This has been a rollercoaster!
