TTC #3! I starting taking my OPK tests the day after my last AF which was March 2nd. I tested low for hormones on the 3rd and 4th, but then today...BAM peak fertility!!! I didn't even get a "high" fertility indicator.  Has this happened to anyone else? Glow had to back track my fertile week by going back 2 days where it now says my fertile week began 2 days ago rather than today. Does that make sense? .
