Last week on monday i was 2.5 cm dilated & last night i was having badd contractions 4 mins apart so i went to L&D & i was dialted to 4. They kept me over night but said they wouldnt give me meds to help labor but they also wouldnt stop my contractions. They checked me again at 7 am & i hadnt made any progress so they let me go home. Im still having contractions, but not as strong. Wen should i be expecting REAL labor?
