Not necessarily: Ideally, one would like a cycle or two to pass bewtween the miscarriage and pregnancy, but it's not necessary.

Few things: Sorry to hear about your miscarriage. It's likely that your positive pregnancy test is related to your last miscarriage. I'm an on/gyn in your area and if you want to call my office later today i would be happy to further discuss this with you. 956-992-0730.
