Subutex

Please no bashing. Long story short, I had a drug addiction. I started counseling, and was also put on subutex to control withdrawals and cravings. I found out I was pregnant two weeks into treatment. I immediately started lowering my dose under my doctors supervision. My obgyn is supportive. We have high hopes for no complications or withdrawal once the baby is born and I'm praying hard! Anyone mommies going through this? I went from 8 mg to 4 mg. I'm feeling very rough at night and I've been told any slight withdrawal can hurt the baby and cause preterm labor or slow heartbeat which can end badly. So I'm trying to keep my body stable all while trying to be on the lowest dose possible. I'm asking for prayers and strength for my baby girl and myself. Any suggestions experience or comments are appreciated! I'm almost 32 weeks
