Honestly, I think you should talk to your doctors about it, both your OB and your pain doctor. Together, they should be able to come up with a plan that will allow for you to take some pain meds while still keeping the baby healthy. Its no good to have you in pain constantly which as you said is causing depression and can possibly cause blood pressure problems which can harm the baby. I've known people to take it when absolutely necessary and the baby was born perfectly normal and healthy. I wish you the best of luck and congratulations on the baby!
