STI? BV?

Obviously going to preface this that I’m calling the Gyno first thing tomorrow morning.

Something it’s up with my vagina. Last week it started itching like crazy so I thought I had a yeast infection but then the itching went away. Then I became super swollen down there and I took one of those drug store ph test and I couldn’t even really stick it in me because I was so swollen. But the test quickly saying my ph is abnormal. Well the swelling seems to have gone down however now I’m noticing the smell is off and my discharge is a little off.

Has anyone every experienced symptoms of an STI and if so what where they?
