Menstrual Issues While Taking Yaz: Your Questions Answered - Obstetrics and Gynecology

Yuezi usage and menstrual cycle issues?


Hello doctor, I have been taking Yaz for the fourth month now.
I started taking the first pill on the first day of my period, but my period always comes 2-3 days before I finish the white pills.
I immediately start a new pack on the first day of my period.
Is this correct? My last period started on January 2nd, and I took the first pill of the new pack that day, but today is only the 19th, and it seems like I am experiencing some bleeding (I had sexual intercourse in the early hours of the 19th).
Is this my period? Should I continue taking the remaining pink pills, or should I start the new pack?

Dr. Zhang Kunmin reply Obstetrics and Gynecology


Hello, during the use of contraceptive pills, if menstruation occurs or bleeding happens, there is no need to stop taking the medication; continue to take it as scheduled.
Once the body adjusts to the contraceptive pills, abnormal bleeding will cease.
However, if irregular bleeding persists for more than three months or if there is heavy bleeding, it is advisable to consult a physician for guidance.
Thank you! Wishing you peace and health.

When it comes to understanding menstrual issues while taking Yaz, it's essential to clarify how this birth control pill works and what to expect during its use. Yaz is a combination oral contraceptive that contains both estrogen and progestin, and it is designed to regulate menstrual cycles, reduce menstrual symptoms, and prevent pregnancy.

Firstly, it’s important to note that when you start taking Yaz, you should begin on the first day of your menstrual period. This is the correct method to ensure that the pill is effective right away. If you started taking the pill on the first day of your period, you should continue taking the pills as directed, even if your period starts to occur while you are still taking the active pills (the colored pills).
From your description, it seems that you are experiencing some irregular bleeding or spotting, which can be common, especially in the first few months of taking a new contraceptive. This is often referred to as "breakthrough bleeding" and can happen as your body adjusts to the hormones in the pill. It is not unusual for women to experience light bleeding or spotting during the first few months of taking Yaz, and this does not necessarily indicate that you are not protected against pregnancy.

Regarding your question about whether to continue taking the remaining pink pills or to start a new pack, you should continue taking the pills as scheduled. The pink pills are the active pills, and you should finish the pack before starting a new one. If you experience bleeding while on the active pills, it is generally not a cause for concern unless it is heavy or accompanied by severe pain.
If you had unprotected intercourse and are concerned about the possibility of pregnancy, it is advisable to take a pregnancy test if your period is late or if you experience any unusual symptoms. However, if you have been taking your pills consistently and correctly, the likelihood of pregnancy is low.

In summary, continue taking the remaining pills in your current pack, and once you finish, start the new pack as scheduled. If the irregular bleeding continues or if you have any other concerns, it would be wise to consult with your healthcare provider. They can provide personalized advice and determine if any adjustments to your contraceptive method are necessary.
Additionally, if you find that the breakthrough bleeding is bothersome or if you have other side effects, your doctor may suggest trying a different formulation of birth control that may be better suited for your body. Remember, it can take a few months for your body to fully adjust to a new hormonal contraceptive, so patience is key during this time.
