5 weeks postpartum and struggling with intimacy 😔 what is wrong with me 😔

I’m 5 weeks postpartum, I’ve been on the contraceptive pill for 2-3 weeks and my sex drive is zero which is fine because I’ve just had a baby.....

but even intimacy is difficult, I don’t want to be touched at all😔

I love my fiancé! Very much and we’ve recently been talking about making a proper start on our wedding plans, we have a little girl and have just had our little boy so there is little time for intimacy anyway.... but I’m worried about us... I know that having a baby, breast feeding and the contraceptive pill are all things that can contribute to loss of sex drive but not even wanting him to touch me?? (Even a cuddle) he has said I’m different with him 😔 what is wrong with me ?!?!
