Sex drive :(

Guys I used to be the horniest person ever and I’ve been with my fiancé now and living together sexually active for about a year and a half now and it was super crazy Fun sex all the time in the beginning. We went through a miscarriage in September and my sex drive hasn’t been the same since I know it’s so hard for him and me too but it’s literally like my lady parts shut down for business I hardly even masturbate anymore! I feel like somethings wrong with me it makes me so sad and depressed and I feel bad for him and guilty I’m just not into it. We’ve beeen through a lot together in the past 7 months we stilll have sex I say 2-3 times a week but my drive used to be like once or twice a day and without I would even masturbate everyday!!! Is this normal?? I’m 25 and on the pill been on it for like 7 years now but this is starting to effect my relationship he is sweet and understanding but I know it bothers him he even says he thinks it’s him and if he was hotter blah blah I’m like nooo it’s not you idk what it is!! What do I doooo any advice? Is this normal or should I get this checked out?
