If You Miss a Period
Many women who are normal and healthy do, on occasion, miss a period. This may happen more often when the hormones responsible for the menstrual cycle are shifting back to normal — after childbirth, as breastfeeding is being slowed down, and sometimes during early puberty and toward mid-life.
Pregnancy is the most common cause for a missed period in healthy, sexually active women. There are a wide variety of other reasons why a period may be missed. Stress, illness, excessive exercise, starvation diets or severe calorie restrictions, obesity and some medication errors (like with birth control pills) may all contribute to missing a period. Remember to follow up with your physician for any and all concerns.
