BV or yeast infection? Please help!

About a year ago I had BV and took the perscribed medication and took care of it. I had a pap smear and std/sti test and everything came back good, 4 days later my vagina starts itching badly and discharge turns into white cottage cheesy like. I spoke to my doctor and she prescribed me fluconazole 150mg. I just took it 9/29 in the night time, now today my discharge is this ?????

Do I have BV? Please help I'm very frustrated
