He hasn’t wanted to have sex

Hubby and I are 30 years old and have been together for 17 years and he just doesn’t want to have sex at all it’s been over 2 months, and before I get comments on him having a medical condition it’s not we has to have yearly checkups due to high blood pressure and Afib and they ask him all those question and his work schedule is where he works 3 days only (Weekends) and I’ve made hints to him and wear stuff to turn him on and nothing, he is just not showing interest at all and it makes me feel like a worthless unattractive women. I have told him about it and he says nothing that it’s all in my head but I track when we have sex on this app just incase we would get pregnant. We are home alone Monday threw Thursday as our kids are in school for leaning but nothing he just would rather sit and watch Tv, or bitch about something not being done the way he wants it done.
