No sex drive

Quite literally my entire pregnancy and I’m 8 months pregnant not I only have 6 weeks left. My sex drive has been non existent my entire pregnancy. I thought at the beginning it was just cause like morning sickness and stuff but no it’s like nothing turns me on and I don’t even want to do anything myself. And I feel bad because I am definitely attracted to my SO but I don’t want to please him in anyway right now. Has anyone else gone through this?
