Wtf is this?!

🌸 Crystal 🌸 • TTC #1 since January 2014

So this rash popped up a few days ago first on my stomach, and now on my hands , I have an appointment Thursday but I'm wondering what the hell this is. Has anyone had or seen this before? They are fluid filled with water, like a blister would get.

Nothing new (soap, detergent, nothing has changed), only have seasonal allergies, it's not hives, not pregnant (I'm in my tww),itches like hell... Any thoughts?

Thanks in advance 😊
