Discharge.... 27 weeks

So I have been having lots of pelvic pressure and cramps as I went to see the doctor, they said it’s from liniment pain from baby girl growing and moving, she’s very low to where it feels like she is kicking my but literally... but now I’m having lots of thick white discharge none of this has happened with my two boys it was the same for both of them. But it’s like I’m peeing myself but when I go to the bathroom it’s lots of white thick discharge.... is this normal? What’s going on? I have never had this problem....
