ERRIN birth control

Hello mama’s! Quick question has anyone been on ERRIN birth control?? My doctor prescribed it since I’m breastfeeding. I have seen a lot of horrible reviews on it but there’s quiet a few good ones as well… my husband and I have been using pull out method before we tried getting pregnant for almost two years so I’ve never been on birth control. I tried it once when I was 15, the pill cause I have bad ovarian cysts. I’m really anxious to start it. I have a newborn baby and I know this is a very time strict pill. Have any of y’all tried this? What’s your story if so?
