Itching all over

Constance • Updated: my daughter is now almost 7 months old and I'm no longer a single mother. Me and her father got back together
I'm 30 weeks and have been itching all over (mostly on calves) very badly for almost two weeks now, is this common or should I be worried? I have also felt less movement from my baby in the last few days. I called my OB but they are closed today so I called the emergency number and the lady I talked to said not to worry that it's probably just dry skin. I have a OB appointment Tuesday, should I just wait till then or go to the ER? Thanks!
