Hives

Hi there, anyone has chronic hives? Our baby was a surprise (in a good way) but I was taking antihistamines and am worried about the risks to my growing baby. My doctors all said that the antihistamines are perfectly fine though and also okay continue taking the antihistamines. I tried to stop the antihistamines but ended up not having good sleep due to extreme hives at night.. it is stressing me out :(
