Emergency contraceptive pill issues


I would like to ask, I have been using the oral contraceptive pill "Yueji" for the first time.
I started taking it on the first day of my menstrual cycle, and now I have been taking it for two weeks.
I have been experiencing light bleeding, and I heard that this is a normal phenomenon as my body adjusts.
However, the amount of bleeding has suddenly increased over the past two days.
Is this normal?

Hello, it is recommended to start taking the birth control pill on the fifth day of your menstrual period.
If you feel that the dosage is not sufficient, it is advisable to switch to a different type of birth control pill next time.
Wishing you good health.

More Info


Breakthrough bleeding while using emergency contraceptive pills (ECPs) or regular birth control pills can be a common occurrence, especially during the initial months of use. When you start taking hormonal contraceptives, your body undergoes adjustments to the new hormone levels, which can lead to irregular bleeding patterns, including breakthrough bleeding.
Breakthrough bleeding is defined as unscheduled bleeding that occurs between menstrual periods. It can happen for various reasons, including hormonal fluctuations, missed doses, or the body adjusting to the new hormone levels introduced by the contraceptive. In your case, since you started taking the contraceptive pill on the first day of your menstrual cycle, it is possible that your body is still adjusting to the hormones.

The fact that you have experienced a small amount of bleeding for two weeks is not uncommon, especially if this is your first time using hormonal contraception. However, the sudden increase in bleeding over the last couple of days can be concerning. While it may still be within the realm of normal, it is essential to monitor the situation closely. If the bleeding becomes heavy, or if you experience any other concerning symptoms such as severe pain, dizziness, or an unusual odor, it is crucial to seek medical attention promptly.

In general, breakthrough bleeding should decrease over time as your body adjusts to the contraceptive. If the bleeding persists beyond a few months or if it becomes bothersome, it may be worth discussing with your healthcare provider. They may consider adjusting your dosage or switching you to a different formulation that may be better suited for your body.

It's also important to remember that while breakthrough bleeding can be a normal side effect, it does not indicate that the contraceptive is ineffective. If you have taken your pills consistently and correctly, you should still be protected against pregnancy. However, if you have concerns about potential pregnancy due to missed doses or other factors, it may be wise to take a pregnancy test or consult with your healthcare provider.

In summary, while breakthrough bleeding can be a normal side effect of starting hormonal contraceptives, the increase in bleeding you are experiencing warrants attention. Keep track of your symptoms, and do not hesitate to reach out to a healthcare professional if you have any concerns. They can provide personalized advice and ensure that your contraceptive method is working effectively for you.
