Green Tinted Discharge

Hi, I am almost 4.5 months postpartum.

Since 2 months postpartum I have had yellow and green discharge. I was also having bleeding every time I orgasmed or had sex. I have been tested around 10 times for different infections by my OB which have all been negative. I did test positive for a UTI at 3.5 months postpartum. I took the course of antibiotics and felt better, but the green discharge continued and the bleeding after sex/orgasm stopped. I don’t always have it, it comes and goes now. I am due for my period in a little over a week and now have green tinted EWCM. I go see my new OBGYN next week.

Has anyone ever had this and not had an infection?? I dont want something to be wrong, but my OB acts like I am overreacting at this point because all the tests show no infection. But seeing light green discharge concerns me, as I have never had this happen before. I am at a loss.
