Estrogen cream

Anybody been prescribed an estrogen cream like Premarin? I wasn’t healing on my own and they said it’s likely due to lack of estrogen since I’m breastfeeding. I’m 7 weeks postpartum and still not released. I go back in a little over a week to get checked again but it doesn’t feel much better after a week of using it. It’s also supposed to help with vaginal dryness but that doesn’t feel any better either. 🤷🏼‍♀️
