Why do you stop having a period while you are on birth control?!
Question:
Why do you stop having a period while you are on birth control?
Answers:
it depends on what pill you are on. some of them let you have only 4 periods a year, some are still monthly.
The first 21 pills have a combination of synthetic estrogen and progesterone hormones. The Pill stops ovulation, preventing the ovaries from releasing eggs. The Pill also thickens cervical mucus, making it harder for sperm to enter the uterus. The hormones in the Pill prevent fertilization. The last 7 pills of a 28-day pack have no hormones and are called spacer pills.
