A few weeks ago I had gotten strep throat . When I got the medicine for strep I ended up getting a side effect where my vagina was itchy. I thought it was a yeast infection . It lasted a few days and when i thought it was done I had sex with my bf. I know I wassupposed to but I didn't pee right after I waited about an hour. That very same night I woke having to frequently use the bathroom. As soon as I felt it   I took garlic pills I ate pineapples , baking soda water ,vinegar and i stopped  having to pee . Over the next couple of days it had gotten a littler better , I didn't need to use the bathroom as much but when I did it was extreme like as soon as I felt it it was like I had been waiting for ever and I almost peed on myself. During the time I peed like right where's my vaginal opening is and my inner labia begins to itchy and it only lasts for a few minutes . It been 17 days since my symptoms began. It doesn't itch as badly and and I don't have burning pee as badly . It's about a 3. I just came on my period also. Is this a really bad yeast infection or an sti?
