When it comes to the effectiveness of birth control pills, timing and adherence to the prescribed regimen are crucial. In your case, since you started taking the birth control pill (Diane) on the fifth day of your menstrual cycle (March 6) and have been taking it correctly for 12 days, you are indeed in a good position regarding contraceptive effectiveness.

Generally, most combination birth control pills, which include both estrogen and progestin, become effective after seven consecutive days of use. Since you began taking the pill on the fifth day of your cycle, by the time you reach the 12th day, you should have achieved adequate contraceptive coverage. This means that you can rely on the pill for effective contraception, provided you have taken it consistently and correctly during this period.

It is important to note that if you had unprotected intercourse during the first seven days of taking the pill, there is a risk of pregnancy. However, since you have been taking the pill as directed for 12 days, you should now be protected against pregnancy.

In addition to understanding the effectiveness of the pill, it is also essential to consider the potential for missed doses. If you miss a pill, the effectiveness can decrease, and you may need to use backup contraception, such as condoms, until you have taken the pill consistently for seven days again.

Furthermore, if you are considering switching to a different type of birth control or have any concerns about side effects, it is advisable to consult with your healthcare provider. They can provide personalized advice based on your health history and lifestyle.

In summary, since you have been taking the birth control pill correctly for 12 days, you should have effective contraception. Always remember to take your pills at the same time each day and consult your healthcare provider if you have any questions or concerns about your birth control method.
