just check if they have codeine in them. i know you arent allowed codeine whilst pregnant. otherwise ring the freecall Health Direct and ask what is best option for you while pregnant.
You are actually allowed codiene. I was recomended to have Panadol + Codeine (panadeine) with a toothache I was having.

It is IBUPROFEN that you arent allowed to have. That is in Nurofen, Advil, Disprin, Aspirin etc

Panadol and panadeine are fine to take the recommended dosage (stated on the packet).
