scared to death is this baby time

Sammey • I am 22 years old.! I am married to A wonderful man.! Who I love very much....
Okay lady I am due October 25,2016.
Which makes me 37 weeks and 2 days. 
Every once in A while some thing down low  will start to hurt and it gets tight and then loses back and forth I am not sure what it is that is doing this.
And also I feel like I have to use the bathroom when this happens 
And I am also cramping like I am about to my period....
