This might be labor!!!!

Called OB after being woken up at 5:30 am with contractions 15 mins apart, by 9:45 am they were 10 min apart. They told me to come in to the office checked cervix dilated to a 1.5 in. Told I could go to hospital or home to progress, went home ate and have been drinking lots of fluids, and a cup of raspberry leaf tea. Been bouncing on my ball for 2 hrs and contractionswent down to 5 min apart and now 3 min apart. Trying to make it another hour and a half before heading in to the hospital, or if my water breaks. This could be it!!!!!
