Contact the doctor call for your OB office. I had my wisdom teeth taken out 2 weeks ago and the dentist prescribed me lortab, but I called my doc first just to confirm it. Also, if you're still in your first trimester, I would try to avoid ALL medications as the first trimester is the most sensitive stage of pregnancy.
I don't see it on my list of safe medications list. The only thing on there is Tylenol other than natural remedies, so I don't know.
