Just wanting some input from others!!

I feel like I should know what to expect since this is my second but I’m just as clueless this time around 😅🤷🏻‍♀️. Okay for 3 evenings in a row now I have been getting what I think are contractions. I have slight cramping constantly but every 10-15 min my stomach tightens starting at the top and going down to where I am cramping and makes my cramps about twice as intense for 45 seconds or so. It doesn’t really hurt just more uncomfortable than anything. I have taken baths, drank more water, tried snacking, tried resting, and tried moving but nothing really makes it go away. They last from mid day till I fall asleep.
