Missed taking the pre-emptive contraceptive pill and took the emergency contraceptive pill instead?
Hello, doctor.
I have been taking YAZ birth control pills consistently.
My last menstrual period was from October 20 to October 24.
I missed two pills on October 28 and 29, and on October 30, I experienced light bleeding and took the missed pills that evening, continuing to take two pills for the next two days.
On October 31, I had intercourse with ejaculation, and on November 1, I took emergency contraception and stopped taking YAZ on the same day.
From November 4 to November 8, I experienced bleeding again, which was heavier, similar to the flow I had before starting YAZ.
1.
Normally, I would expect my next period to start on November 16, but it hasn't arrived yet.
Should I calculate this cycle starting from October 28 or from November 4?
2.
Should I resume taking YAZ, or wait until the first day of my next period to start again?
3.
I have been experiencing intermittent mild abdominal pain, similar to what I usually feel one or two days before my period.
I recently took a pregnancy test, which showed one line.
Is there still a possibility of pregnancy? Thank you for your response.

Hello, the first day of your menstrual period should be November 4th.
It's too late to start taking birth control pills for this cycle, so you should begin taking them on the fifth day of your December period.
You should not get pregnant.
Wishing you good health.

More Info
When it comes to missed birth control pills, particularly with a regimen like YAZ, it's essential to understand how to manage your cycle and the implications of missed doses. Based on your situation, here are some insights and recommendations.
1. Understanding Your Cycle: You mentioned that your last menstrual period was from October 20 to October 24, and you missed pills on October 28 and 29. After missing those pills, you experienced light bleeding on October 30, which could be breakthrough bleeding due to hormonal fluctuations from missing the pills. The question of when to start counting your cycle can be a bit complex. Generally, the first day of your menstrual cycle is the first day of your period. Since you had significant bleeding starting on November 4, you might consider this as the beginning of a new cycle. However, since you missed pills and had irregular bleeding, it’s best to consult with your healthcare provider for personalized advice.
2. Resuming Birth Control: If you have not had a period by the expected date (around November 16), it is advisable to wait until you have your first day of bleeding before resuming YAZ. This is crucial because starting the pill again without a clear understanding of your cycle could lead to further hormonal imbalance. If you do not get your period and are concerned about pregnancy, it’s wise to take a pregnancy test to confirm.
3. Pregnancy Concerns: You mentioned having light abdominal pain similar to pre-menstrual symptoms and that you tested negative for pregnancy. While a negative test is reassuring, it’s important to note that false negatives can occur, especially if the test is taken too early. If you continue to experience symptoms or if your period does not arrive, consider retesting in a few days or consulting your healthcare provider for further evaluation.
4. What to Do Next: If you decide to wait for your period to resume YAZ, keep track of any symptoms you experience. If you do not have a period within a week or two after your expected date, it would be prudent to consult your healthcare provider. They may suggest further testing or an alternative method of contraception until your cycle stabilizes.
5. General Advice on Missed Pills: In general, if you miss one pill, take it as soon as you remember. If you miss two or more pills, the guidance typically suggests using backup contraception (like condoms) for at least seven days after resuming the pills. Always refer to the specific instructions provided with your birth control, as different formulations may have varying recommendations.
In conclusion, managing missed birth control pills requires careful attention to your cycle and symptoms. It’s crucial to communicate with your healthcare provider to ensure that you are making the best decisions for your reproductive health. They can provide personalized guidance based on your specific situation and help you navigate any uncertainties regarding your menstrual cycle and contraceptive use.
