real deal?

I feel like i have to go to the bathroom but i dont and then my stomach tightens up and then my back gets uncomfortable,

I doubt it. It's probably more like Braxton Hicks. If they increase in intensity and the time between them shortens, I would worry.

It could be early labour. With my first son when my labour first started I wasnt even sure if it was the real thing or not because I felt like I had to poop but couldnt, I didnt know it at the time but the poop feeling was actually contractions. I would time them. If they seem to be every 4-5 minutes apart I would go get checked. good luck
