Input on possible early labor?

Shelby
Is this early labor, I've had consistent back pain and cramps. Then last night I had this horrible pain in my pelvis and then increased pain in my back. I also had an uncontrollable mental and emotional breakdown for an hour last night. I tossed and turned most of the night unable to get comfortable and the pain hasn't stopped even if I move positions of drink water. 
This morning I was laying and couldn't hold still for a minute cause I was uncomfortable and while making breakfast I had to keep sitting down because the pain was getting so unbearable while standing. 
I have noticed for the past 20 minutes I've felt like I needed to poop, but I just can't. I just feel like I need to. Has anyone had anything similar? 
Please don't just say, "I'd go get checked or call the doctor"
