I am at a loss with TTC

It has been 14 long months. One chemical pregnancy. A husband who has a low sex drive and doesn’t have the desire to have sex multiple times in a week. We got in a huge fight because I told him we should have sex two the other day, so we did. It was two days before I got a positive OPK (I thought I’d get one a day earlier), and he said we wasted it. He tried having sex with me the day of the positive OPK but he was hardly in the mood. I can’t just not tell him I’m ovulating because seduction won’t work. It has to be such a planned out think with us, and that makes it harder. Whoever said “making the baby is the fun part” is so wrong. He also recently told me that he doesn’t really want to seek medical help (no tests, no procedures). I think he’s afraid of the possibility of finding out his sperm are below average. Ugh, he’s fed up, I’m fed up. But I want this too badly to give up 😭
