Hi!
If you were my patient, I would advise you that Benadryl is safe during pregnancy. As with any medication you should only use it when it is really indicated (eg such a a reaction to bee stings).
Good luck!

My doctor told me it was ok to take it before. When you start going to the doctors you can ask for a list of medications you can take.
I was told not to take it till about 13 weeks. So talk to your doc.
