First time being pregnant here! Need help!

Last couple days I’ve just been so achey. I haven’t had any full blown cramps that cause me pain but my lower back is just crampy on an off and there is no consistency. I can be fine for a few hours and then I’m back to feeling lowsy with some mild menstrual type cramps. So mild. Yesterday I had several bowel movements, like I couldn’t stop and today haven’t had any. Idk I just feel off and idk if I should worry and consider this early signs of labor or what. I’ve been pounding the water and laying down, taking it easy. I’m only 36 and 1. :/ anyone else have this going on and then go into labor shortly after or am I just being worried for nothing? Idk what labor feels like. So lost.
