Possible UTI/Yeast Infection, so confused!!!

Okay so for the last week and a half when I go to the bathroom it has been hurting when I pee. I've drank a lot of cranberry juice, water, I've tried OTC products for a YI & it's eased up a lot but won't go away. Well the last 3-4 days I've had a gooey discharge. It started a brownish color but now it's almost clear with pinkish "chunks". I ask family & they say possible implantation bleeding, but I thought it only lasted for a day or two? I'm calling to make an appointment first thing tomorrow. But anyone have any thoughts on this?
