It kinda stinks down there, but I have no infection...help?

Mia

Ok so when I go to the restroom I can smell it and it seems like the smell is kinda based on what I ate, irdk tbh but I've had a somewhat "pee infection" that when I used to restroom it's like I had to go rly bad, even tho I just peed, but also when I'm doing normal stuff I would have to go to the restroom like every 5 minutes...can that also be the cause of the smell?? And btw I'm 12 so I need some advice, and answers on what's going on and see if anyone else has gone through this??
