NO Sex drive

So in the past year- year and a half my husband and I have had sex like 4 or 5 times. I have no sex drive. I got pregnant in may last year and no sex drive while pregnant. Had my son in january and had a sex drive till around my 6weekpp mark and its gone again :( I just want to have sex with my husband and enjoy it. between no sex drive and the ongoing spotting I've experienced since I had my son we have had sex twice since he was born in january. I didnt enjoy it i thought if i went through with it id feel better :( this sucks. does anyone have any advice or had this happen to them? please help :(
