Pressure mounting at ovulation

Hi all, need advice. We have been trying for about five months. But we’ve really hit ovulation days maybe three times total. We were one of those couples that thought they’d get pregnant right away (lol). Our sex life has always been amazing. But TTC is getting to us. Last month my husband and I had sex two of the days leading up to ovulation but then on the high fertility days, my husband felt really stressed about the pressure to do it and he had issues. I then got annoyed. This month I’m trying not to freak out. I just tested and I started high fertility window last night. We had sex a ton last week and last night, once again, my husband had issues. I am not telling him I am testing but I am guessing he knows/remembers. I think I put out a stressed out vibe and sex as an obligation obviously is a mood killer for all. What can we do? This is a lot. What do some people do when this happens? We’re at five months but I can’t imagine it getting easier. It frustrates me SO much that we can’t just hit the important days. It makes me feel shitty like everyone in the world literally can’t but us. Do someone people do IUI or home insemiantion for when this happens?

Thank you so much in advance. I am pretty dejected.
