Having two menstrual periods?


Hello doctor, I started my period on November 9th.
On the fifth day of my period, November 13th, I began taking the emergency contraceptive pill Ella (ulipristal acetate).
However, on November 24th, I experienced a second period, with the first 2-3 days of discharge being brownish, followed by bright red blood.
I still have my period as of December 1st, but the flow is not as heavy as my previous periods.
Is this normal?

Please visit a gynecologist for further evaluation.

Irregular periods can be a source of concern for many women, and understanding the underlying causes and implications is crucial for managing reproductive health. Based on your description, it seems you experienced an early onset of menstruation after starting a new contraceptive method, which can be quite common.
When you began taking the contraceptive pill (in this case, Alicean), your body may have reacted to the hormonal changes introduced by the medication. Birth control pills work by altering hormone levels to prevent ovulation, and they can also affect the menstrual cycle in various ways. It is not unusual for women to experience irregular bleeding or spotting, especially during the first few months of starting a new contraceptive method. This phenomenon is often referred to as "breakthrough bleeding."
In your case, the coffee-colored discharge you observed before the bright red blood could be a sign of old blood being expelled from the uterus, which is common during the initial adjustment period to hormonal contraceptives. The fact that the flow was lighter than your usual menstruation is also not uncommon, as hormonal contraceptives can lead to lighter periods for many women.

Here are a few key points to consider regarding irregular periods and early menstruation:
1. Adjustment Period: When starting a new contraceptive, it can take a few cycles for your body to adjust. During this time, irregular bleeding or spotting may occur. If you continue to experience irregularities after a few months, it may be worth discussing with your healthcare provider.

2. Hormonal Fluctuations: Hormonal contraceptives can lead to changes in the menstrual cycle, including the timing and flow of periods. Some women may experience shorter, lighter, or even missed periods while on the pill.

3. Underlying Conditions: If irregular periods persist, it may be indicative of underlying conditions such as polycystic ovary syndrome (PCOS), thyroid disorders, or other hormonal imbalances. These conditions can affect menstrual regularity and overall reproductive health.

4. Consultation with a Healthcare Provider: If you have concerns about your menstrual cycle, especially if the irregularities continue or worsen, it is advisable to consult with a healthcare provider. They can perform a thorough evaluation, including a physical examination and possibly blood tests, to rule out any underlying issues.

5. Tracking Your Cycle: Keeping a record of your menstrual cycle, including the start and end dates, flow characteristics, and any associated symptoms, can be helpful for both you and your healthcare provider in understanding your menstrual health.

In summary, while experiencing irregular periods after starting a new contraceptive is often normal, it is essential to monitor your symptoms and consult with a healthcare provider if you have ongoing concerns. They can provide personalized advice and determine if any further evaluation or intervention is necessary. Remember that every woman's body responds differently to hormonal changes, and what is normal for one person may not be for another.
