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.
During the first stage of labour your cervix â the neck of your womb â dilates to a rather incredible 10cm (yes, we did say 10) so that your baby can squeeze his or her way out. Understandably, this can take a while â typically, at least 12 hours in a first pregnancy (although it can be much longer).
