peeing

Em
When I pee, I finish and then I have to pee again not even 2 minutes later. And I've been having a creamy white discharge. I've had a UTI before and they're really irritating and can be itchy, I'm not having any irritation besides the constant need to pee. Any one have this problem or know what it is. 
I've also been having pains in my stomach (between my hips but below my belly button) not constant only sometimes
