I think if I were you I'd be going back to the doctor to get another blood test or scan or something. I've never had an ectopic, but I did have a missed miscarriage, and the pregnancy symptoms that remained after my baby had died did vanish pretty quickly after the D&C. I wouldn't know what's going on, but it sounds like something I'd want to get checked out.

Sorry that you are going through this.
