Should I go to the ER?

I dont have insurance yet. Im currently on a wait right now at my job. I have about 2 months before I can qualify for insurance. The problem is I think I may have Pelvic Inflammatory Disease(PID). A couple years ago I did get a STD from a guy I was dating but I went to Urgent Care and got a shot and was given pills to take. I took all my pills and was fine. In the past couple of years I realized I have smelly discharge. I orginally thought it was a yeast infection So I got Monistat and that didnt work. I dont have any itching or uncomfortable pain. Its just ALOT of discharge and it smells. Its creamy white. From time to time the right side of my pelvis will swell and hurt but then it goes down. Im afraid the ER will turn me away due to no insurance. I dont want to ruin my reproductive system. I actually want a huge family. Im not willing to wait 3 months. Ladies what do I do?
