Normal to cramp at 33weeks preg?

The cramps started last nite and went away after about 2hr...and they just started back...they feel like period like cramps...I went 2 the doc on mon cuz I been havin sharp pains inside my and she said I was 1cm dilated but the baby wasn't engaged...soo im wondering if I should call her and let her know that im cramping or if I should go 2 L&D...also I have been drinkin big cups of water all day and it hasn't helped any..im also laying down with a pillow under my feet..really need 2 know if I should call my husband and worry him cuz he works 1hr away from where we live...
