Ladies any suggestions would be great...

Earlier this week, I thought I had BV, as after sex, I smelled a slight fishy smell. The doctor prescribed me medication, however, the next couple of hours after that, there was no smell. I've had intense itching and burning around the vaginal area, even my anus.

I used a Monistat ovule last night (3 day), and while I've noticed a slight change, I am still very itchy. Anyone have any thoughts moving forward? This is the first time my vagina has ever felt like this! Was tested in September and all STD panels came back negative. I've only been sleeping with the same partner since then.

We are not exclusive so I'm wondering if it's more than a yeast infection??
