Subutex..

I have been doing Subutex for a while, started about 2 years ago and I was able to stop as soon as I found out I was pregnant with my daughter who is 9 months now. I’m pregnant again but only around 5 weeks. I have become dependable for the Subutex but not getting them subscribed. I was winging myself off about a week ago and felt fine until last night I was going absolutely crazy, I couldn’t sit still, I couldn’t sleep. I want to stop for the health of my baby but I don’t know how. I don’t want baby to withdraw at all and I’m ready to just be done with it. Has anyone had experience with this? Please don’t judge, you don’t know my life. I just need helpful advice. My OB doesn’t know about the Subutex I couldn’t tell her without feeling as if I was gonna be judged
