Any clinics that I can get free/cheap STDs check in Malaysia?

I think I have gonorrhea. The symptoms match up.
I know it's not the worst of STDs, but I think I need to see a doctor as soon as possible so that the symptom doesn't get worse.

I've felt the symptoms for a while now and noticed that it's getting worse.
I have visited two clinics in Damansara. It would cost me RM250 just for a check-up and I really can't afford it.
Anyone can suggest a clinic that can offer cheaper STD check-up and treatment?
