hives from birth control???

I just started Junel fe 1/20 and it’s been a week since starting it. The past 3 days, an hour after I take it I get hives all over my legs. Wtf? Is this normal? Has this happened to anyone else? I’m not allergic to any foods. I don’t have any pets(not allergic anyways). I haven’t used new detergent or touched or used any new lotions or perfumes or soap or shampoo and conditioner... like literally nothing. The only new thing is the birth control. It’s not possible to be allergic to birth control. Wtf.
