lower belly pain.

Tiffani • Army WifexDec262015
Im 37weeks and 1 day. 
I been feeling period cramping like pain on my lower belly. 
Should i got into the labor & delivery? Or just not worry because its nothing? 
Also having strong lower back pains.
FTM.
UPDATE: Went to labor & delivery.
So im 2cm & 75% effaced. Waiting on my urine sample to see if it was my kidneystones that caused the cramping. 
Other then that, being sent home & baby girl is doing great!
