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.
The second stage of labor begins when you're fully dilated and ends with the birth of your baby. This is sometimes referred to as the pushing stage. The third stage begins right after the birth of your baby and ends with the delivery of the placenta. Every pregnancy is different, and there's wide variation in the length of labor. For first-time moms, labor often takes between ten and 20 hours. For some women, though, it lasts much longer, while for others it's over much sooner.
