Oral contraceptive pills


1.
I would like to ask if it is normal that my period started on July 15, which was the fourth day after stopping the medication on July 11, after taking the first pill of Yuezhi on the first day of my period on June 21 and finishing all 21 pills.
2.
Should I start taking the next pack on the eighth day after stopping the medication, which would be July 19, or should I start on the first day of my period, July 15?

Huang, 20~29 year old female. Ask Date: 2023/07/15

Dr. Cao Guotao reply Obstetrics and Gynecology


Hello, it's normal.
Generally, birth control pills are started on the fifth day of your menstrual cycle, and your period will typically occur within a week after finishing the pills.
Wishing you good health!

More Info


Understanding oral contraceptives and their relationship with the menstrual cycle can be a bit complex, but I’ll do my best to clarify your questions.

1. Is it normal for menstruation to start a few days after stopping the pill?

Yes, it is quite normal for your period to start shortly after you stop taking oral contraceptives. When you take a combined oral contraceptive pill (like the one you mentioned, which is likely a combination of estrogen and progestin), it works by maintaining hormone levels that prevent ovulation and regulate your menstrual cycle. When you stop taking the pill, the hormone levels drop, which can trigger withdrawal bleeding, similar to a menstrual period. This bleeding typically occurs within a few days after stopping the pill, and it can vary in timing from person to person. In your case, starting your period on the fourth day after stopping the pill is within the normal range.

2. When should you start the next pack of pills?

The general recommendation for starting your next pack of oral contraceptives depends on the type of pill you are using. For most combination pills, you should start taking the next pack after the 7-day break, regardless of whether you are still experiencing your period or not. In your case, since you stopped taking the pill on July 11 and your period started on July 15, you would typically wait until the 7-day break is over and then start your next pack on July 19.
However, if you are using a different type of oral contraceptive, such as a progestin-only pill or a different regimen, the instructions may vary. It’s always best to follow the specific instructions provided with your medication or consult with your healthcare provider for personalized advice.


Additional Considerations
- Cycle Regularity: If you notice significant changes in your menstrual cycle after starting or stopping the pill, such as irregular periods, heavy bleeding, or prolonged absence of menstruation, it’s important to consult with your healthcare provider. They can help determine if these changes are normal or if further evaluation is needed.

- Effectiveness: Remember that oral contraceptives are most effective when taken consistently at the same time each day. If you miss a pill or take it late, it can reduce the effectiveness of the contraceptive. Always refer to the patient information leaflet that comes with your medication for guidance on what to do if you miss a dose.

- Other Contraceptive Methods: If you are considering switching methods or have concerns about side effects, discuss these with your healthcare provider. There are various contraceptive options available, including IUDs, implants, and non-hormonal methods, each with its own benefits and considerations.

- Health Monitoring: Regular check-ups with your healthcare provider are essential while on hormonal contraceptives. They can monitor your health, discuss any side effects, and ensure that the method you are using is still the best option for you.

In summary, your experience with starting your period shortly after stopping the pill is normal, and you should begin your next pack after the 7-day break, regardless of your menstrual status. If you have further questions or concerns, don’t hesitate to reach out to your healthcare provider for guidance tailored to your specific situation.
