Effects of birth control pills on monthly periods

We all are aware that birth control pills are a medium to prevent pregnancy. Let’s peep a little further to explore the effects of these birth control pills on the monthly menstrual period.

Regulate menstrual cycle

When the body doesn’t ovulate regularly, one can have irregular, heavy, and bleeding in-between the periods. Sometimes doctors prescribe birth control pills to regulate and normalise such periods as the pills can help in having a control over the hormonal levels. The hormones (oestrogen and progesterone) in birth control pills help in regulating the menstrual cycle so that the period comes every 28 day.

Delay periods

There are times when women want to skip or postpone their periods due to an upcoming event, vacation, honeymoon, or for any other personal or medical reason. The pills come in handy at that time too.

A typical pack of birth control pills contains 28 tablets, where only 21 are active (containing hormones to suppress the fertility). The rest seven pills are inactive. The bleeding that occurs during the fourth week when the inactive pills are taken is withdrawal bleeding, which looks like a period. If one skips the inactive pills and start a new pack of active pills right away, there won't be any withdrawal bleeding or period.

Eliminate monthly periods

There is another type of birth control pill called the “mini-pill”, which is a low-dose progesterone-only pill. It does not have any oestrogen. When women take this low-dose birth control pill at the same time every day, they will not get a period until they stop taking it completely.

Decrease the frequency of menstrual periods: In a recent breakthrough formulation, the combination birth control pill can be taken for 12 weeks in a row. This decreases the frequency of monthly periods from once in a month to once every three months. This low-dose progesterone pill can reduce the frequency of menstruation and one can stop it and induce a period as per their convenience.

Pleasant effects:

Most women experience lighter and shorter period, when they are on birth control pills. These lighter periods are healthful because not much iron and other nutrients are lost during the monthly flow.

Women, who complain of severe abdominal cramps during the period, also experience a much relaxed and pleasant cycle.
