Help!

I had a miscarriage on the 25th of March,.. but still bleeding last week my HcG level was 80 on Wednesday then 106 on Friday and today 150... the gyn want’s me to come back Next Tuesday for a scan and a new HcG bloodtest.

With the previous scan we saw nothing there (last week),.. if I was pregnant,. Then I am suposed to be 9 weeks,..

I am scared it’s something dangerus,.. Have someone experienced the same?

Happy thoughts :)
