I was checked on Tuesday, and im 32 weeks ( i was checked because i have a short cervix to begin with, and i was getting it measured and the ultrasound showed i was dilated ) I was sent to the hospital and checked, i was 1cm dilated, but had no stomach cramps. Well I just left my OB office; and was checked again because they wanted to see how much i was dilating within a few days, and im 1.5-2cm, but now im feeling crampy and stuff.
