lots of cervical mucus after miscarriage

Kirsty
I had a miscarriage 3 weeks ago. After the bleeding stopped, I consistently seem to have cervical mucus like I'm ovulating for 2 weeks now. Has anyone else have this? What does it mean? The dr told me to wait out a cycle but I'm scared that I've suddenly got very fertile and I'm wasting it! (it took 2 years for me to fall pregnant) Any advice would be much appreciated. Xxx
