Jen...does you dr prescribe them to you or are you taking them on your own?
None of us can answer for sure if it would harm your baby or not. I can tell you that my dr did RX them to me later in my pregnancy due to the same issues you are having and I limited my use as well and my son is fine. He was born early only b/c of my high blood pressure and so they took him about 6 weeks early. Also, before I found out I was pregnant I was taking them for my back pain and stopped the day I found out I was pregnant and my OB was fully aware of all of this.
I just want to make sure your OB KNOWS YOU ARE TAKING THEM!!!
Congratulations by the way and is this your first baby?
This has to be something your Dr knows about. At those doses it amy be OK but only your Dr is the one to answer this.
i took percocets at about 7 months for severe sciatica. back then, i took them when i was supposed to, as prescribed..like 2-3 a day 5mg. you should be just fine taking those. my doc and ob told be if the well being of the mother out weighs the risk, then they will prescribe that kind of stuff. like everyone else said though, i would tell your doctor about this. take care and congrats on the baby:)
