Congrats on your pregnancy. I hated being pregnant too and did not bloom at all.I had terrible sickness and when that ended got gestational diabetes ended up on insulin and was worried something would be wrong with the baby. It's worth it though.
Look after yourself, put yourself first,rest and try not to make too many demands on yourself-don't expect too much of yourself.
I wouldn't tell your obgyn about your recovery. If you are sober now and have been all pregnancy there's no risk to your baby.If you tell them it's on your file and they may well involve social services. I wouldn't take a chance.You could just say you don't want pain meds. I had a section so can't really advise.good luck
