When do uterine contractions start?
Braxton Hicks contractions can begin as early as the 20th week of pregnancy, but most often they start between the 28th and 30th week.
How far does a cervix need to dilate before a woman can start pushing?
The cervix must be 100 percent effaced and 10 centimeters dilated before a vaginal delivery. The first stage of labor and birth occurs when you begin to feel regular contractions, which cause the cervix to open (dilate) and soften, shorten and thin (effacement). This allows the baby to move into the birth canal.
What is abnormal uterine contraction?
abnormal uterine action are numerous and sometimes lead to confusion. There are basically two groups of abnormal uterine action that may cause dystocia. The resting uterine muscle tone may be poor (hypotonic) and result in feeble or no contractions, or the muscle tone may be high (hypertonic).
