How to take birth control pills?


Hello Doctor: I usually take the contraceptive pill Aijie, and my period typically starts three days after I stop taking the pills.
This time, due to special circumstances, I need to delay my period by a week, so I took an additional week of pills from a new pack, leaving me with 14 pills in the second pack.
After my period starts this time, should I continue taking the pills on the fifth day by finishing the 14 remaining pills, or do I need to take an additional week of pills from a third pack?

Dr. Chen Zhiyu reply Obstetrics and Gynecology


Regarding your concerns, I suggest that you do not continue taking any remaining medication, regardless of the amount.
You should start anew with the first dose of the new medication.
If you have any doubts, it is best to consult a healthcare professional.
Thank you for your inquiry, and I wish you health and happiness.

When it comes to using birth control pills, it's essential to understand how they work and the best practices for their use. Birth control pills, or oral contraceptives, are a common method for preventing pregnancy. They contain hormones that regulate the menstrual cycle and inhibit ovulation. Here’s a comprehensive guide on how to properly use them, especially in the context of your situation.


Understanding Birth Control Pills
1. Types of Pills: There are two main types of birth control pills: combination pills (which contain both estrogen and progestin) and progestin-only pills (often referred to as the "mini-pill"). Combination pills are the most commonly prescribed.

2. How They Work: Birth control pills work primarily by preventing ovulation. They also thicken the cervical mucus, making it more difficult for sperm to enter the uterus, and thin the lining of the uterus to prevent implantation.

3. Regular Use: For maximum effectiveness, birth control pills should be taken at the same time every day. This consistency helps maintain hormone levels in your body.


Managing Your Cycle
In your case, you mentioned that you typically experience your period three days after stopping the pills. However, due to special circumstances, you chose to extend your cycle by taking an additional week of pills from a new pack.
1. Continuing After Extended Use: After you finish the second pack (which you have 14 pills remaining), you should continue taking the pills as directed. Since you are on a combination pill and have taken an extra week, you can finish the remaining pills in that pack.
2. Starting a New Pack: After you finish the 14 pills, you should start a new pack immediately if you wish to continue preventing pregnancy. You do not need to wait for your period to start a new pack. This is often referred to as "back-to-back" pill usage, which is safe and can be beneficial for managing menstrual symptoms or timing.

3. After Your Period: Once your period comes, you can continue taking the pills from the new pack as scheduled. If you have any concerns about your cycle or the effects of taking the pills continuously, it’s advisable to consult with your healthcare provider.


Important Considerations
- Missed Pills: If you miss a pill, follow the instructions provided with your medication. Generally, if you miss one pill, take it as soon as you remember. If you miss two or more pills, you may need to use backup contraception for a short period.

- Side Effects: Be aware of potential side effects, which can include nausea, headaches, mood changes, and breakthrough bleeding. If you experience severe side effects or have concerns, consult your healthcare provider.

- Consulting Your Doctor: Since you are managing your cycle in a non-standard way, it’s always a good idea to discuss your specific situation with your healthcare provider. They can provide personalized advice based on your health history and needs.


Conclusion
In summary, you can finish the remaining 14 pills in your current pack and then start a new pack immediately afterward. This approach will help you maintain effective contraception and manage your menstrual cycle according to your needs. Always remember to consult with your healthcare provider for personalized guidance and to address any concerns you may have regarding your birth control method.
