No Sex Drive

hi all I had my son 5 months ago. bad labor and delivery that ended up with a c section. in the 5 months since having our son. my husband and I have had sex once. I have no want at all. my husband is being really sweet but I know he is miserable.

I breastfeed which I know doesn't help but my sex drive is 100% gone. I really have no want.

Advice please.
