Husband not wanting to BD

Hear me out, my husband and I have a VERY healthy sex life... we have recently started trying to conceive and said we would do it with zero pressure and just “let it happen”. Well of course being the planner I am, I’ve been <a href="https://play.google.com/store/apps/details?id=com.glow.android">tracking ovulation</a> and Wanting to BD the correct times... we have a healthy sexy life, but we both go through days of each of us not wanting to, but lately I feel soooo frustrated when he says he’s too tired or not in the mood because it seems to fall on prime days for baby making.I don’t want to sound pressuring and make it unromantic strictly to possibly make a baby, but I’m so frustrated... I feel like this app almost makes me crazy and I should just not even know my ovulation days so I don’t worry about it. Thoughts??? Anyone going through the same thing?
