Hives

Anyone else get really bad hives in pregnancy ? I was traveling when I started breaking out . I was visiting family in California when I broke out . I live in Kentucky . What should I do to get rid of them ? They’re severely itchy and I can’t sleep because of them . I’ve taken some Benadryl and it helps a little but eventually wears off . Me and my boyfriend slept in the same bed the entire time and he has no spots . Also more and more spots are popping up even now that I’m home . Also I’ve had these for almost a week now .

UPDATE : I went and seen the doctor . She said it’s definitely hives . She believes I had allergic reaction to something I came in contact with . Thanks for all the replies everyone .
