Yellow/green discharge 23 weeks helps

Yellow/green discharge, worried about infection.

I'm 23 weeks and been suffering from awful symptoms down below for weeks- burning, redness, itching, frequent urinartion, pain when weeing, tender tummy, braxton hicks.

I was told to just take a pessary for potential thrush and had a urine sample sent off- no results back yet.

It has got particularly green past few days and more discharge. What do i do? I definitely have an infection as really period crampy down there. I feel like no one is listening to me and the infection is going to spread and cause pre term labour🥲
