Causes of a Missed Period while on the Pill
The hormones found in oral contraceptives control the natural flow during menstrual period. This phenomenon produces lighter bleeding and a shorter period. However, some experience missing a period which can cause alarm to sexually active women. Here are the following reasons for a missed period while on the pill:
Missing a Pill
It is important to take the pill regularly to ensure its effectiveness. That is why many of the birth control pill dispensers have labels or numbers to indicate the corresponding day when each should be taken. Missing a pill increases the chance of getting pregnant. If one tablet is missed, it is important to take it as soon as one realizes that it was skipped. However, if more than one pill was missed, it is best to consult your physician for advice.
Effect of the Pill
New medications taken can cause some disturbance in the menstrual cycle. The synthetic hormones found in birth control pills alter the menstrual cycle, thus producing change in the blood flow as well as the duration of the period. Certain types of oral contraceptives such as Depo-Provera and Norplant can cause a missed period. This effect disappears in time, once the body has adjusted to the changes in the hormone levels.
As mentioned previously, it is important to take the pill regularly to achieve its optimum effect. It is recommended that those who have just started taking a pill should use other contraceptives during the first seven days of use, particularly for sexually-active women. Pregnancy is likely to occur during this period, that is why it is best to have additional means of contraception. In case pregnancy is suspected, it is best to take a pregnancy test as soon as the first day of a missed period to alleviate any anxieties.
