Yeast infection? Someone help..

Elle

So I started having symptoms of a uti (itchy, burny when I pee, after I pee it feels like I still have to go) so I go to Walmart and talk to the pharmacist and he shows me AZO uti over the counter meds. I started taking them yesterday so my pee has been bright yellow/orange. I went to the bathroom just now and it felt like something was /inside/ my vagina. I looked down and there’s a white ‘chunk’ coming out. Can someone help me figure out what this is? I’ve had multiple utis in the past but this has never happened.

The picture is from when I wiped after seeing the white chunk.

It’s about an inch long, and about as wide as my pinky.

My fertile window ended 3 days ago and my period is supposed to start in 10 days.
