Hives from Clomid...

So I've been breaking out in hives here and there all over my body and I'm guessing it's from my Clomid because it started on my 2nd day of taking the Clomid right before I went to bed. It's weird to me because this is my 3rd cycle of taking Clomid and I didn't break out the other 2 times I took it. So I was gonna just toughen it out since today and tomorrow are my last days for taking Clomid but I'm gonna call my dr today first because it's getting a little worse. I would wake up in the middle of the night and find myself scratching my arms and back ect.
