Babysmurf,
Do you feel contractions that peak after awhile? If the contractions are near, you can go Kkh immediately.
That time, I also pain, I thought is I constipation pain at 1+am till I spot bloody discharge at 4am. If u worried, can just go labour ward for peace of mind. I went 2 times then but only 1cm dilated. Only third time went in then 4cm, then deliver on same day over a period of 4 days.
