Currently on cycle 7 TTC #1. I track BBT everyday and in the past have used OPKs after work (5pm-ish. I can't see how I can test during the day) but never had a positive result so currently stopped using them. BBT does spike for about 2 days a month around day 20 and we make a concerted effort to DTD in the days leading up to and after but still no BFP.
How long should we keep trying before making an appointment to see the doc? I'm 36 (and overweight which I'm trying to sort out) and DH is 37.
