Birth control pills, sold in packs of 21 and 28, are used as a method of preventing pregnancy. The back of the package indicates one pill for each day of the week. If you are using birth control pills for the first time, the first pill is usually taken on the day your menstrual period begins. However, taking the pill within the first 5 days of your period will not reduce its effectiveness. To keep track of which days you take it and establish a routine, you can start with the day indicated on the back of the package and continue from that day.
If you are using birth control pills containing 21 pills, you should take a one-week break after finishing your first pack. Your period will occur on any day during this one-week period. This time, you should start a new pack seven days after the end of the previous pack (i.e., on the eighth day), regardless of when your period starts. There is no need to wait for your period to stop. Using the pill on the first day of your period is only applicable to those starting a new pack. For subsequent uses, you can continue using the pill regardless of your period day.
The package contains 21 pills, to be taken one per day. When taking the pills, try to take them at specific times each day. For example, if you take your pill at 8 PM, you should try to take it at the same time the next day. Differences of 3-4 hours are not a problem, but taking the pills at different times each day may reduce their effectiveness. Taking the pills on a full stomach is healthier because it reduces the risk of nausea, but this is not a factor in the effectiveness of the pill. Taking it on an empty or full stomach does not affect its effectiveness.
If you miss a birth control pill for one day, you should take two pills the next day. Missing it for two days reduces its effectiveness. If you miss it for two days, you should use an additional method of contraception that month.
28-tablet packs of birth control pills are no different in effectiveness from 21-tablet packs. The only difference is that the remaining 7 pills do not contain hormones. These 7 pills are empty and contain only iron. The usage of the 28-tablet pack is the same as with the 21-tablet packs.
The Effectiveness of Birth Control Pills
If the first pack is started within the first 5 days of menstruation and used regularly without skipping a day, the protective effect begins with the first pill. There is no decrease in protection during the 7-day break between pills. However, if a new pack is not started after these 7 days, the protective effect of the medication ends and the risk of pregnancy increases. Birth control pills are a highly effective method of contraception. New generation birth control pills contain low doses of estrogen, so they can be used safely until the woman decides to become pregnant.
