I've always had irregular periods (anywhere between 30-37 days but usually around 36 days. One time it was 50 days). It's currently CD41 and AF hasn't come. I started BBTing late (I know I'm supposed to start at the beginning of the cycle but I charted anyways). I've taken a pregnancy test past Friday and this morning but BFNs. We've been TTC for about 10 months now. I think I should see a fertility specialist since I have such irregular periods and I'm about to turn 31. Any thoughts?
