Gyno Related Question

So I've been having a lot of watery discharge and at first I thought it was a yeast infection so I got treated for yeast. However, a week later nothing has changed so I went back to the gynecologist for STD testings. The doctor thought I had chlamydia so she gave me antibiotics along with yeast infection medicine. Confused and shocked, I thought I had chlamydia. However, I just got my results back and I was negative for all STDs. The one reason why I'm asking a question on here is because my insurance ended on the last day of July and I don't have the funds to go back to the gyno with no insurance. So could anyone give me an educated guess as to why I would be having a lot of watery discharge and when I go to the bathroom, there are white chunks at the bottom of the toilet? My doctor said there was a lot of white blood cells in my test which is why she thought it was chlamydia but now I'm at a dead end and I'm not sure what to do. Thank you for reading!
