How to lose weight after birth

I’ve already lost all my baby weight but I’m still not happy with my body 😔 especially after finding out my husband was watching amateur porn videos and all from this one girl who was really skinny and I’m just not skinny now that I had a baby 5 weeks ago... I weigh 190 and hate it. How can I lose extra weight? (I’m not breast feeding. I was but couldn’t anymore due to lip and tongue tie (milk dried before I could get them clipped.)
