Hello lady's , before I go any further I do have a appointment this wensday for a ultrasound so I plan on asking my doctor but wanted to see if anyone else has experienced this. 
I am currently 21 weeks pregnant , everything had been normal til now... Around Christmas I noticed when I changed soaps my vagina became super ichy so I figured I needed to change soap.. So I did and it helped some.. Then it come back and I had some thick white discharge mixed in with the normal clear ... Now I'm complectly dry no discharge hardly ever but been I do have discharge my vagina lips ich so damn bad that I wanna scream... 
I never did this before or with my first pregnancy ... Any insight would be very very appreciated !! Thank to all and happy new year !
