I don’t know what this is???

Ok so I started the Depo shot December of last year. I recently had my second shot a few weeks ago and there’s this stuff coming out of my vagina. I can’t even describe it. A few months ago, my gynecologist told me that I had BV, so she sent the medication over to my pharmacy and I took it and it cleaned up, but recently, my boyfriend came in me and after that, I started to get a little itchy down there. Nothing severe, I just looked up the symptoms of BV and pretty much everything matched, so I cleaned and sterilized the applicators for my BV medicine (there was still a lot left in the tube) using warm water and steam and put the medicine in at night like how I did before. But a few days ago, I’ve noticed this stuff when I wipe. Can someone tell me what it is??? I’m really grossed out and scared.
