I talked to my doctor about allergy medicine and he recommended I wait until I was at least 5 month to take anything. So I would definitely ask your doctor before taking anything especially since your just 11 weeks.
You have to be careful tho like clartin d is harmful. My Dr gave me a script for it so i don't have to.worry about remembering what kinds are ok and what aren't
Yes that is okay to take so is Benadryl. Before taking any medicines I would still consult your doctor or pharmacist tho:)
