Anyone struggling with severe allergies?

lovematters

I use to have severe allergies before getting pregnant. Now my medications won't work. My tabs were changed over a week ago from Centrezine/ Zyrtec to Claratine but I have noticed any changes. My nasal sprays aren't helping either. I am miserable in the mornings gets a little better in the day but have to breath through the mouth most of the time. Any tip will be appreciated!
