Funny, I was just speaking with my sis about this very thing. Her OB told her that in the 3rd trimester its absolutely fine to take cold and flu tablets. I think you should check directly with your OB or health care provider rather than a pharmacists. I hope there are no pharmacists out there but I've got to say that I've had some pharmacists give some very incorrect advice in the past and don't trust them.

If you put the information that everyone has posted together then Codral should be fine......
Codral (daytime) contains: Paracetamol, Pseudoephedrine, Codeine
PinkPalace was told she could take panadol (= paracetamol) and sudafed (= pseudoephedrine)
PlonkeeMumma was told she could take panadol and codeine
So that's your ingredients of Codral!

Like I said before though, I think you should check directly with your OB.
