Weird pains?? Please help

I’m not sure if I should be worried or not... beginning a few days ago (I can’t exactly remember when but I know it was around 2-3 days ago) I started getting weird uncomfortable pains. When I begin to pee it kind of aches, not to where it hurts it’s just pretty uncomfortable. It’s more up by my ovaries I believe, I’m young and don’t know much about my body because My school doesn’t offer a girls health class or a sex Ed class. I don’t think it’s anything important just curious? I’m pretty sure this has happened before and it just went away, it’s only on my left side and really only happens when I pee (not a UTI, the pain is a little lower than my belly button)
