Emergency contraceptive pill issues?
Hello, doctor.
I am the person who asked question #197995.
I would like to ask you again: This month, I changed my birth control pill brand from (Yaz 24+4) to a 21-pill formulation.
I finished the last active pill of Yaz on June 16, and my period started on June 19.
I took the last inactive pill of Yaz on June 20.
On June 23, which was the fifth day of my period, I started taking the first pill of the new 21-pill formulation.
I would like to ask you:
1.
There was a 7-day gap from June 17 to June 23 without taking any pills.
Is this gap too long? Will it affect the current contraceptive effectiveness?
2.
On June 25, which was the third day of taking the 21-pill formulation, I had sexual intercourse with ejaculation.
Should I be concerned about pregnancy?
3.
I have taken this 21-pill formulation before, but as of today, June 29, I am still experiencing bleeding (from June 19 until now).
Is this my period?

Dr. Cao Guotao reply Obstetrics and Gynecology
Hello, the correct way to take the medication is to finish the entire course.
Monitor for any abnormal bleeding with the next pack of birth control pills.
If there is still abnormal bleeding, you should consult a gynecologist.
Wishing you good health.

When switching contraceptive pills, it’s essential to understand how the transition may affect your contraceptive efficacy and overall menstrual cycle. Here are answers to your questions based on the information provided:
1. Is a 7-day break between pills too long, and will it affect contraceptive effectiveness?
A 7-day break between contraceptive pills is generally considered significant, especially if you are switching from one type of pill to another. The effectiveness of hormonal contraceptives relies on maintaining consistent hormone levels in your body. When you stop taking the pill, your hormone levels drop, which can lead to ovulation if the break is too long. Ideally, you should start the new pill as soon as you finish the last active pill of the previous pack to maintain contraceptive coverage. Since you had a 7-day gap, there is a risk that you may not be fully protected against pregnancy during this time. It is recommended to use a backup method of contraception, such as condoms, for at least the first 7 days of taking the new pill.
2. Should I be concerned about pregnancy after having unprotected sex on the third day of the new pill?
Since you had a 7-day gap before starting the new pill, your body may not have been fully protected during that time. By the time you had unprotected intercourse on the third day of the new pill, you may not have achieved full contraceptive efficacy yet. Typically, it takes about 7 days of consistent use of the new pill for it to become effective. Therefore, if you had unprotected sex during this period, there is a possibility of pregnancy. If you are concerned about this, you may consider taking a pregnancy test if your period is late or consult with your healthcare provider about emergency contraception options.
3. Is the bleeding I’m experiencing from June 19 to now considered a period?
The bleeding you are experiencing after switching pills could be due to several factors. It might be a withdrawal bleed from stopping the previous pill, or it could be breakthrough bleeding, which is common when starting a new contraceptive method. Breakthrough bleeding can occur as your body adjusts to the new hormone levels. If the bleeding is light and irregular, it may not be a full menstrual period but rather a side effect of the hormonal changes. It’s important to monitor the bleeding pattern over the next few cycles. If the bleeding continues for an extended period or becomes heavy, it would be wise to consult with your healthcare provider for further evaluation.
In summary, switching contraceptive pills requires careful consideration of the timing and potential effects on your menstrual cycle and contraceptive efficacy. If you have any concerns about your specific situation, it’s always best to consult with your healthcare provider for personalized advice and guidance. They can help you navigate any issues related to your contraceptive method and ensure that you are adequately protected against unintended pregnancy.
