Help!!

Erica • 27 years old. Married. 1 daughter, and a son on the way. Due December 30, 2015
Cramping for a little over an hour on and off. 32 weeks 1 day today. Went to labor & delivery on monday with the same problem, they said my cervix was really soft but closed. They told me if this happens again, lay on my left side and drink plenty of water for an hour. Tried that, and it seems like its not helping. Don't know what to do!
