itch and burn

Shannon
I read on the internet that it is very common to have vaginal itching and burning during pregnancy. Anyone else had this problem. I have never had a consistent issue with it. I am probably going to try and get in to my doctor this week just in case it is an infection but after sex this last time I felt like I was on fire!!!  The itching has gotten a lot less but the burning was intense. It got better when I washed off. I am not sure if it is a ph issue with body fluids (his or mine) or what it is. Just curious if anyone else had the issue or not. I have also had more discharge lately but I am almost into my 2nd trimester as well. They say that increases also. Just concerned.
