Partners with back pain, Anyone in the same boat ?

My partner had a work related injury back in December and hasn’t been the same since. He has to take oxy and endone to function on a daily basis. He’s going in for either a disc replacement or fusion in a few weeks. So in saying this our sex life is next to nothing as if he doesn’t take medication he’s in pain and if he does take it he can’t finish...we have only been ‘trying’ for 2 months. But I’m really struggling, it seems that everything revolves around the day I ovulate as it’s so ‘important’ for us to do it than to have a chance of convincing. This month we only did it on our ovulation day and like a week prior and I feel like it’s just going to take us a very longtime. I’ve been ready to be a mum for years and he’s finally like yep and than this back injury happened 🥺

I also had a chemical pregnancy last month which was really upsetting 😔
