I went for a walk yesterday and had hives all over my body. now they came back today. no chg in diet or meds. been ttc. could i be pregnant?

Maybe: Anything is possible, but the best way to know for sure is a urine or blood pregnacy test.

Not related.: In a sense, "anything is possible" but the hive are unrelated. There are rashes that look like hives during pregnancy. At this stage, hives are caused by something else.

Urticaria: You could be allergic to almost anything. Foods, medications, hormonal changes...Pregnancy would not be the first thing that i think about.
