Husband doesn’t want to have sex during fertile window

Alison, 🌈 👶🏻 born 7/26/19

Ive had two miscarriages back to back one in December one in April. Finally after six months of testing, we are in the clear to try again .... I found out I have a blood clotting disorder, I’ve been taking all my supplements , a baby aspirin , progesterone .... and my husband is being a pain in the ass not wanting to have sex. If I tell him I’m in the window he gets turned off. If I don’t tell him he still makes no moves on me. I’m 39 years old and will be 40 in 8 months. My fertility doctor told me if I’m not pregnant by December to come in well how will I know if he won’t even try?!?! If it’s this difficult BEFORE a baby I don’t know why I am wasting my time. .... anyone else have this experience??
