Opinions??

Okay so this might be a little long. ( Im 16)So around April I started a sexual relationship back up with one of my exs. After the second time of us having sex things my vagina started acting wierd. It smelled and my discharge was like water and it burned like hell when I went pee. I then found out he was hooking up with his other ex!! I was so scared that I had a Std because my parents do not know I’m sexually active. So I went to the doctor and I was diagnosed with Bv, I took the medicine for 7 days and the smell went away but things were still off. This annoyed me because it made me think I might have a Std. My discharge became thick and chunky with no Oder and I get a tingling feeling when I pee, but no Uti. I figured I have a yeast infection due to the anti-biotics I was taking to get rid of my Bv. I am now currently taking the 7 day miconazole medicine, the medicine itches and burns about the first 10-15 minutes after application. I’m 3 days in and I’m not seeing results??
