I am so confused. I had an hcg done 2 weeks ago and it had gone down to 843. I still hadn't had a period so the re put me on provera. I hadn't started after that so they drew another hcg yesterday. I got home and thought I was starting af because I had some red blood but nothing today. The re office got my results from the hcg yesterday and it had jumped up to 29,000. The nurse said it could be a lab error, I could still have some retained tissue, or I could be pregnant. I asked if it was normal if I still had some retained tissue for my hcg to go down then jump back up and she said not really but possible. I am going in tomorrow morning for an ultrasound. Any opinions as to what is going on? I am going on vacation in 10 days and was looking forward to not thinking about any IF stuff but now I am wondering if that is possible. I am just ready for tomorrow morning and to see what is going on!
