Hello!

I had a chemical pregnancy last November. Hubby and I decided to wait a little bit before trying again. We started trying 3 months ago and this morning I took a HPT and I got a VERY faint positive line. However, that's what happened in November. Any suggestions on when I should call my Dr. to get a blood test? Last time my levels never went up and that's how I knew and then eventually I miscarried. My AF isn't due for 3 days. So should I wait until after that to go get blood work or go now? Thanks in advance!
