I am only 1 DPO with confirmed OPK and pinching yesterday which is how I knew when to BD with #1 and was successful. My husband and I have been TTC for 13 months and have had a miscarriage and a handful of CPs. Started using preseed this month and BDing everyday in fertile window. I was also laying there for 15-20 minutes after. Glow predicted my most fertile day as yesterday the 15th and was 33%. Which was right as I got a very positive OPK. So here's to hoping we finally have a sticky bean!! Will start testing on the 25th.... ;) CD 19 today.
