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.
Strong Contractions in the Second Stage. The second stage of labor begins with the birth of the first kitten, which should happen around 30 minutes to an hour after Fluffy starts her strong contractions. She'll have rest times between each kitten's birth, usually lasting about 15 to 30 minutes. Depending on how many kittens there are, it can take as little as a couple of hours to a good part of a day for Fluffy to deliver her brood.
