Not sure what you really look like, but as on my own opinion, some girls after giving birth have lost the self care about themselves, specially their looks, but it's not a really big deal though, due to having responsibility specially taking care if the Child/ren will take some of your time for yourself, but your husband should also know what you feel, your struggle, pray it all to God and talk to him in person, not in a complain way but let him realised your current stand.
