Also, visit a healthcare professional about your period if: 1  You havenât gotten your first period by age 15. 2  You donât menstruate for more than 90 days. 3  Your periods start to be very irregular after having previously been regular. 4  Your period lasts for more than seven days. 5  Your menstrual flow is more heavy than usual.
This stage continues until your baby passes through the birth canal, vagina, and is born. This stage may last two hours or longer. Contractions may feel different from the first stage of labor -- they will slow to 2 to 5 minutes apart and last from about 60 to 90 seconds. You will feel a strong urge to push with your contractions.
Most likely what will happen when you go into labor is that you will begin to feel contractions. With some women the water breaks, and then they begin to have contractions. In the first stage of labor, the cervix will dilate from closed, which is its normal state, to fully open at 10 cm in diameter. In mothers having their first child, this stage usually lasts 12 to 16 hours.
