I miscarried early & idk why it's bothering me so much...

I just had a super early miscarriage at only a month and a half and I don't know why but it's really bothering me.. I wasn't even trying and I really cant be pregnant right now anyways for a thousand different reasons, one being so close to my last surgery, two being my husbands job recently made a lot of pay cuts and we went homeless 2 months ago and JUST lost his work car, ect..

I managed to have sex with my husband once since but I just really had a hard time with it and its not him, I know it's me.. I just don't understand why... It was SO EARLY!! I just don't know... I tried today and it upset me too much.. Every time he'd touch me, all I could think is..."you're suppose to be pregnant right now.. You just lost a baby.." And then I'd freak out a little inside. Maybe I just don't want it to happen again? Maybe I'm scared? Maybe it's that I got excited and then lost it.. I don't know.. I know... It's seriously stupid but please, somebody with experience just tell me how to fix it... 😥😢
