Yesterday i was having really strong & painful contractions for about 4 hours. They were lasting 3-4 mins so i headed to the hospital & as soon as i get there they stopped so i was sent back home. Any opinions on this? Does this mean i can go into labor soon? How soon? An hr after they started i went to my doctors office & they said i was 1cm dilated & 50% effaced. Not sure where im at now though...
