“Performance anxiety” while TTC

My husband and I have been TTC for two months now. He is on an anxiety med and I’m on a depression med- both meds have a side affect of low sex drive so before we started TTC we had sex approx. once or twice a week. Now that I have been tracking my ovulation, I will tell him when I’m at my peak and when we should be having sex more often. Tonight, a day before my ovulation when we were about to have sex, he says he has been feeling performance anxiety and feels pressured to have sex. He says I’m not pressuring him but that since I’m ovulating he feels pressured to have sex and “finish”

Has anyone else experienced this with their partner? I don’t know how to not make him

Feel that way. Of course I reacted not the best when he told me because it seemed like he was saying I was pressuring him into sex, when in reality I think he is just nervous about so much at stake. Advice?
