2 weeks postpartum not hungry

So I noticed since having my baby girl 2 weeks ago today that my appetite has disappeared like I know being pregnant I was going to eat like a beast but I am legitimately not hungry anymore if anything I'm eating once a day MAYBE twice a day 😪 I'm not doing it purposely for vanity reasons but I'm seriously not hungry and it's a bit depressing because I feel I'm letting my baby down. Is this just me? Does anyone else have this problem? Should I mention I'm a FTM?
