Yes!!! Last week (when I was 7 weeks)! And it's awful!
I was going to post here about it, but then went out of town last weekend, and was mostly better by the time I got home Sunday night.
If you google "pregnancy hives" there's a ton of info out there. But take my advice and don't google "miscarriage hives" or you'll worry yourself.
Here's my story:
Last Thursday morning (Oct 20) I woke up around 3am with my scalp and neck super itchy. As I started scratching, I noticed my back, tummy, thighs, and arms were also itchy. I got up and went to the bathroom. In the mirror I saw I was covered in hives! I went and woke DH up- he googled it on his phone and told me it was normal in pregnancy and to go back to sleep. Well, I was WAY too itchy to sleep, so I took a benadryl, which helped knock me back out. When my alarm went off (6am) I was barely able to text my boss and let her know I was too sick to come in. I then fell back to sleep till about 10:30am. When I woke up, more hives, still itchy.
I called my OBGYN, who said to keep taking benadryl and call back if it wasn't gone the next day. Friday morning I woke up even worse, called OBGYN back, who said to call my family doctor. I called him and went in Friday afternoon, but he didn't have any good information for me. Said if I wasn't pregnant they could give me a steroid shot, but since I was, then just keep taking benadryl. He said i could use hydrocortisone cream in small amounts. He thought it might have been caused by a virus or was just a weird pregnancy thing, but he ruled out an allergy.
I suffered all day Friday and Saturday. I developed hives on the palms of my hands and the soles of my feet. It hurt so badly to walk. And they were sensitive to heat- it hurt to shower or bathe! Thankfully they started lessening Sunday afternoon, and were totally gone by this past Monday morning.
