Hives?

Has anyone else experienced hives in their first trimester? I randomly broke out last night and they are some better, but now I have a new spot on my butt cheek 🤦🏼‍♀️ where I sleep on my back and my panties bunched up last night. I obviously can’t go to work scratching my butt tomorrow! Help!!! This photo was last night, I broke out worse where my bra, panties and short waistband were, and around my neck and upper chest. I’m about 7 weeks based on my last period. And no I haven’t eaten anything new or changed soap or laundry detergent.
