Discontinuation of oral contraceptives can lead to irregular menstruation?


Hello Doctor, I have been taking Esmya for over three years.
My menstrual period ended on May 27 this month, and I was supposed to start taking the medication on May 23.
However, this month I also needed to take medication for asthma, and I stopped taking the Esmya on the sixth day of the cycle (May 28).
It has been about six days since then, but on the sixth day after stopping the medication (June 2), I experienced bleeding (which seems to be menstrual).
I would like to ask: 1.
Is this a normal phenomenon that can occur after an abnormal cessation of the medication? 2.
When should I resume taking the medication? Thank you.

Lay, 20~29 year old female. Ask Date: 2019/06/02

More Info


When a person has been on birth control pills for an extended period, such as three years in your case with Alesse, and then decides to stop or miss doses, it is not uncommon to experience irregularities in menstrual cycles. Here’s a detailed explanation of what you might be experiencing and what to consider moving forward.

1. Irregular Bleeding After Stopping Birth Control: After discontinuing birth control pills, especially after long-term use, it is common for the body to take some time to readjust to its natural hormonal cycle. The bleeding you experienced on June 2, which occurred six days after stopping the medication, could be a withdrawal bleed. This is similar to a menstrual period but is triggered by the sudden drop in hormones when the pills are stopped. It is not unusual for this bleeding to be irregular, lighter, or heavier than your typical menstrual flow.
The body’s hormonal balance can take a few cycles to stabilize after stopping hormonal contraceptives. Some individuals may experience amenorrhea (absence of menstruation) for a few months, while others may have irregular cycles. This variability is due to the body re-establishing its natural rhythm, which can be influenced by factors such as stress, weight changes, and overall health.

2. Next Steps for Medication: Regarding when to resume taking your birth control pills, it is generally recommended to start a new pack of pills at the beginning of your next cycle. If you have experienced a withdrawal bleed, you can consider starting the new pack as you would normally do at the beginning of your next menstrual period. If you are unsure whether the bleeding you experienced is indeed a period, you might want to wait until you have a clearer understanding of your cycle before starting the pills again.

If you are using birth control for contraceptive purposes, it is crucial to use an alternative method of contraception until you can confirm that your cycle has returned to a regular pattern. This is particularly important if you are sexually active and wish to avoid unintended pregnancy.

3. Consulting a Healthcare Provider: If you continue to experience irregular bleeding or if you have any concerns about your menstrual cycle, it is advisable to consult with a healthcare provider. They can provide personalized advice based on your medical history and current health status. They may also perform tests to rule out any underlying conditions that could be contributing to the irregularities.

4. Understanding Your Body: It’s essential to be patient with your body during this transition. Hormonal contraceptives can significantly alter your menstrual cycle, and it may take time for your body to return to its pre-contraceptive state. Keeping track of your menstrual cycle, any symptoms you experience, and any other medications you are taking can be helpful for discussions with your healthcare provider.

In summary, experiencing irregular bleeding after stopping birth control pills is a common phenomenon as your body readjusts. It is advisable to monitor your cycle and consult with a healthcare provider if you have any concerns or if irregularities persist. Remember to use alternative contraception if you are not planning to conceive until your cycle stabilizes.
