I think I have a l infection...?

For the past week I've noticed I've been extremely dischargy, like to the point that I have to wear a panty liner. also it smells fishy, within the past month I've had a UTI and a yeast infection and I don't think this is the same. I'm not ually active but I have been fingered, can you get anything from being fingered if there is not bodily fluids being transfered? And what do you think this could be?
