Does it sound like i have an STI? Should i question my bf about it?

So when i was 18 and sleeping around, i got Chlamydia. Symptoms were fishy discharge and a VERYY painful stinging pee where 1 drip comes out. Ive given birth, but i remember how painful that was. Once i took the meds it cleared. My symptoms now arent that strong tho.

Currently i have a boyfriend of 1 1/2 yrs. And were both loyal. Ive never had a UTI before, but 2 weeks ago, i think i got one. I had to pee often and it stung. I had to pee in the middle of the night urgently too. It went away basically. My problem is, i still have to pee sort of often and i only feel the tiniest pressure at the end as if it didnt fully go away. But i feel normal again and healthy/ fine. The thing is my discharge is sour smelling?? Not through my clothes or anything. But sour discharge for the past few weeks. I drank so much water and took probiotics and it still hasnt gone away. Im embarrassed to have sex. My bf cant tell. But i can. I know when i smell on point and when i smell off. Im saving $ to go to a clinic to get tested and swabbed for BV but i cant for a few weeks/ months Does this sound like an STI?? I dont think my boyfriend would ever ever cheat hes loyal and open. Weve been dating a year and a half. Could this be BV? An STI? Or a subtly UTI? Has anyone had this problem before? Advice would be helpful before i can get checked with a doctor
