In women, progesterone levels are relatively low during the preovulatory phase of the menstrual cycle, rise after ovulation, and are elevated during the luteal phase, as shown in diagram below. Progesterone levels tend to be < 2 ng/ml prior to ovulation, and > 5 ng/ml after ovulation.
Results for this Gallup poll are based on telephone interviews conducted Aug. 7-Dec. 29, 2013, on the Gallup Daily tracking survey, with a random sample of 3,445 adults, aged 18-34, living in all 50 U.S. states and the District of Columbia, who report they are currently living at home with their parents.
For instance, if both parents work for the same employer, under CFRA, a total of 12 weeks of leave is permitted for both parents. This means that mom can take 5 weeks and dad can take 7, or mom can take 10 weeks and dad can take 2, but there is a twelve week limit on the total amount of leave that can be taken.
