cramping in my lower stomach only the right side

I got a pain in my lower right side by my knicker line what is it is it anythink to worry about??? ..

I am “right side” 🤣

Can contractions be one sided? I woke up to this on and off pain in my right lower abdomen/pelvic area.. I sleep on my left side anyways, but I've peed, drank water, laid on my left side to see if they will stop and they haven't.. Currently laying on my right side and it is continuing???

So I keep feeling these lil sharp pains on my right side. You do get pains like that before you start your period right.? Remember I had that dark brown spotting for a few hours last month on the 22. My period suppose to start today.
