Last month my husband and I BD 2 days before my peak fertility day, then 1 day before the, the day of.

I thought we had finally done it right and my bfp would be on the way. However, my period come right on time, and I was heartbroken.

Now this time around my window is coming up soon, and I am feel anxious about messing up.

I temp, and use opk to track my ovulation. It seems to happen at the end even after the window Glow provides me. Could that be the issue? If not, what am I missing?

Any help is appreciated.
