Menstruation and Menopause
The menstrual cycle is the process by which a woman's body gets ready for the chance of a pregnancy each month. The average menstrual cycle is 28 days from the start of one to the start of the next, but it can range from 21 days to 35 days.
Most menstrual periods last from three to five days. In the United States, most girls start menstruating at age 12, but girls can start menstruating between the ages of 8 and 16.
Pregnancy and preconception care
Pregnancy is the term used to describe when a woman has a growing fetus inside of her. In most cases, the fetus grows in the uterus.
Human pregnancy lasts about 40 weeks, or just more than 9 months, from the start of the last menstrual period to childbirth.
What are prenatal and preconception care and why are they important?
In addition, health care providers are now recommending a woman see a health care provider for preconception care, even before she considers becoming pregnant or in between pregnancies.
Both preconception care and prenatal care help to promote the best health outcomes for mother and baby.
