We have been trying for about 5 months. The only things that I did differently this cycle was use the Ovacue Mobile fertility monitor, watch my CM, and bbt. I have very irregular periods and OPKs were predicting my ovulation window at an earlier time. My body attempted to ovulate twice in one cycle. I think this was happening in other cycles, so we were missing our fertile windows completely. Ovacue helped me see the trends in my cycle and help us BD in the correct window. If you're having trouble getting pregnant, I HIGHLY recommend investing in Ovacue Mobile. It worked for me in one month!
