BinkBear "It was in the bin with food waste and would have been taken out tomorrow. I’d be happy to put it in the bathroom bin but DH won’t allow us to have one because he thinks it’s unhygienic." Ah OK, sorry, didn't notice that.
Well I think he needs some help here. I'd say just have your own bin in your bedroom (we have a swing top mini bin with a bin liner, might help but my guess is he would find that diffiuclt too. It sounds like it i not all about periods so it's much bigger than that. It's weird what different people feel is odd. DH hates used cotton buds, I hate hearing people clip their toe nails, but neither drives us into a frenzy.
Re "A couple of weeks ago he screamed at me because I wiped a drip of saliva off the baby’s chin with my hand instead of using a muslin cloth. I’m convinced he wasn’t this bad several years ago when we met."
I do think maybe your dh has some issues here and it may be worth exploring them, getting some help. I've had some therapy and although my OCD probably won't ever go away it's certainly totally manageable now.
When dd was little and I was doing nappies I was washing my hands a lot because it worried me, I managed my OCD but my darling husband did get some of it in terms of my door checking! "Have you really locked the door!" Asked lots of times! He did not collude with me, just told me once and that was it. He helped me.
I wonder if your dh needs some help with this. It's not easy admitting you need help and the responses on this thread show there isn't just one answer to what might be a normal way of doing things. But shouting at you etc is not on and he needs to know that.

Good luck.
