Ovulating on my period.

Erica • Momma-to-be in Sept 2019! 🤰🏻
So today I took my first OPK, and as you can tell by the pic it is a blazing strong positive.
But my husband who wants this as badly as I do tried to BD with me but couldn't because unfortunately AF isn't all the way done. What the hell do I do? We are both so frustrated. How long do I have? We're going to try again later today is that okay?
