Its day 3 of my period and Ive noticed an increase in the urge to pee . I go pee and I still feel like theres some left. Like the feeling you get when you hold your pee too long, is this normal?

My doctor told me I had a uti back in February, but I didn't have any burning sensations or pain when peeing.

I don't think it's pregnancy cause ive received all periods since having sex over three months ago..
