Hives while pregnant

Help!! Has anyone else gotten hives while they were pregnant?? I had my first check up with my GP today and mentioned it and how bad they were the previous day and he just basically ignored me. Needless to say i’m switching GPs anyhow, but i did tell him i caved and took an antihistamine because i was in so much pain last night and he just said i shouldn’t have done that. Well then?? Ugh. Help ladies!! I’ve no idea what to do and it’s on my legs, chest, sides, arms and esp. armpits! Didn’t change anything in my diet, environment, etc. also i put on hydrocortisone but it doesn’t really help 😭
