I think I have PID

Should I see a doctor? I’ve been ttc for a year, I’ve already been a couple times about this but they’ve just sent me away with no help because I’m young. I have been told I have polycystic ovaries but as I have regular periods and blood tests show I’m ovulating, they think I won’t have a problem conceiving and I don’t think that’s the problem either. I think it’s something more. Today I’m really worried as I never get period pain, but this cycle I have really bad pain. The last time I had pain this bad was before I got pregnant with my son 2 years ago when my periods used to be bad. I’ve also noticed a lot more discharge then normal this month, no weird colour or smell though. And a few sharp pains around my belly button/abdomen throughout the month. I don’t wanna keep going back to my doctor and annoy them with my worries, all they do is send me away and don’t seem to listen. Does it sound like I’m just being paranoid, or is it worth going?
