Allergies?

Ariel
Anyone take Benadryl for allergies? I have two kitties, and pre-pregnancy I took Zyrtec everyday to deal with them. Now after doing some research, Benadryl seems to be the safest of allergy meds during pregnancy
And before anyone suggests it: No, I am not getting rid of the cats just because I have itchy eyes and a runny nose. 
Just want to make sure it is not harmful to baby. And I cant wait to ask my midwife about it on Wednesday!!!!
