Sex feels like a job

I’ve been TTC for 7 months, we usually BD every other day during my fertile window, my cycle is normal, I ovulate on time... and nothing. This cycle we were going to try to BD every day during the fertile window but night 3 (Valentine’s Day) he says he feels like it’s a chore and he’s not into it (while we’re in the middle of BD’ing). He says he just got frustrated he couldn’t finish and didn’t mean what he said, I’m upset because I feel like he’s not attracted to me or he’s over trying....
