Do early contractions make you feel like you have to go to the bathroom?

I keep getting a cramp-y feeling on both my lower back and front of my pelvis & every time I do, I start feeling like I have to either poo or pee. I'm 39+2. I don't really know if I'm timing them right cause sometimes the cramp-y feeling around my whole lower midsection lasts like 2 minutes. I didn't think they were supposed to last that long
