Birth control pills


Hello, I have been taking Dailian for six months and have been taking it on schedule.
On December 29, when I took it as usual, I forgot whether I had taken it on December 28, so I ended up taking an extra pill on the 29th.
I felt a bit dizzy afterward.
I would like to ask if I should continue taking it on the 30th, or should I stop and wait for my next menstrual period to resume? Thank you.

Hello: If you forget to take your birth control pill, you should take 2 pills the next day and continue taking them as usual.
If you experience light bleeding, you can still continue taking the pills.
Your dizziness may also be related to the side effects of the birth control pills; this side effect is generally not a cause for concern.
Taking a short rest or switching to taking the pills before bedtime can help alleviate the symptoms.

More Info


When it comes to missed birth control pills, it's important to understand the implications and the appropriate steps to take to ensure continued contraceptive effectiveness and overall health. Based on your situation, you mentioned that you have been consistently taking your birth control pill, Daili'an, for six months and that you forgot whether you took your pill on December 28. Consequently, you took an extra pill on December 29, which has left you feeling a bit dizzy. Now, you're uncertain whether to continue taking the pill on December 30 or to stop and wait for your next menstrual cycle.

First and foremost, it’s crucial to clarify that missing a birth control pill can potentially reduce its effectiveness, depending on how many pills you have missed and when in your cycle this occurs. In your case, since you are unsure whether you took the pill on December 28, taking an extra pill on December 29 was a precautionary measure. However, taking two pills in one day can lead to side effects such as nausea, dizziness, or headaches, which may explain the dizziness you are experiencing.

Here’s what you should do next:
1. Continue Taking Your Pills: Since you are unsure if you took the pill on December 28, the best course of action is to continue taking your pills as scheduled. You should take the pill on December 30 as you normally would. This will help maintain the hormone levels in your body and ensure that you remain protected against pregnancy.

2. Monitor for Side Effects: After taking an extra pill, it's common to experience some side effects. If the dizziness persists or worsens, or if you experience any other concerning symptoms, it would be wise to consult with your healthcare provider.

3. Use Backup Contraception: If you are concerned about the effectiveness of your birth control due to the missed pill, consider using a backup method of contraception, such as condoms, until you have taken your pills consistently for seven consecutive days again. This is particularly important if you have unprotected intercourse during this time.

4. Consult Your Healthcare Provider: If you have any lingering doubts or if you experience significant side effects, it’s always best to reach out to your healthcare provider. They can provide personalized advice based on your medical history and current situation.

5. Keep Track of Your Pills: To prevent future missed pills, consider using a pill organizer or setting reminders on your phone. This can help ensure that you take your pill at the same time every day, which is crucial for maintaining its effectiveness.

6. Understand Your Cycle: If you decide to stop taking the pill, be aware that your menstrual cycle may take some time to regulate, and you may not have immediate protection against pregnancy. If you are considering stopping the pill for any reason, discuss this with your healthcare provider to understand the implications.

In summary, continue taking your birth control pill as scheduled, monitor any side effects, and consider using backup contraception if you feel uncertain about your protection. Always consult with your healthcare provider for personalized advice and guidance tailored to your specific situation. Taking these steps can help you manage your birth control effectively and maintain your reproductive health.
