Hallow Dear,
From your question, I guess this is your first
pregnancy.
During first pregnancy, the effacement of the
cervix takes place much before - may be about one week before the woman goes in labour. Your cervix is just 50% effaced; however, the cervix has started dilating. According to WHO definition, the woman is in active labour when the cervix is more than 4 cms dilated.
During last few weeks, woman does start appreciating the contractions of the
uterus. In fact the uterus is continuously contracting and relaxing throughout the pregnancy; however, there is no perceivable pain. These contractions are called Braxton Hick's contractions. When woman goes in labour, these contractions become stronger and woman starts getting pains. The labour contractions start at the lower back and radiate in front. then they are coming from above downwards. Successively, the intensity, duration and frequency of true labour pains go on increasing.
When you are in labour, along with the pains, there is frequency of urination and there is blood stained mucous plug (show) found at the vaginal opening.
From your history, you seem to be in imminent labour. You may start labour pains within a week's time.
Wish you happy motherhood. Please start
breastfeeding the child within half an hour of the delivery and for six months, give the baby exclusive breast feeding.
