BV?? Yeast infection??

So after my last period, things have been a little off down there. Not exactly sure what’s going on, but maybe you guys can give me better insight. So, my discharge is really thick and kind of cottage cheese like, I thought it was a yeast infection. But the smell it carries is terrible, and a yellowish color. Which is why I thought it was BV could it be both? And what can I do to get rid of it?
