STD or UTI

I know I know I know 1st things 1st GET TESTED or rather rewind time and USE PROTECTION (but we’re past that point). Seeing that tomorrow is Sunday and clinics are closed I figured why not ask a bunch of ladies who might have been in my shoes before. I have an uncomfortable pain in my lower abdomen which subtly affects my back. And when I pee it (doesn’t sting) but I notice an odd feeling towards the end. None of the pain is detrimental it just isn’t normal and 1st thing Monday morning I will get tested but in the meantime has anyone gone through this before??
