Maybe a UTI? idk

Ka

Hey ladies i need some advice. So all day long yesterday i had the feeling like a needed to pee, but when i went hardly anything came out. Today i don't really feel like i have to pee but when i go, the usual amount comes out however at the very end i get this shooting pain. Not like a burning sensation but like an ache almost. Any ideas of what this could be? My fertility window ends in 2 days, idk if that has anything to do with it.
