Postpartum body

I have PCOS and a few years ago I weighed almost 250 lbs well over the course of about 3 years I dropped down to 160. Last year I suffered 2 miscarriages and a successful pregnancy with in 4 months in that time I creeped up to 180 at the beginning of my successful pregnancy and ended my pregnancy at 226. I am now 212 and it is killing me I hate my self and the way I look. I feel as though I cannot lose any weight. my daughter is 2 months old now and I have not lost anymore weight. With PCOS it’s so incredibly hard to lose weight. Any advice from anyone?
