Early Menstruation While Taking Contraceptive Pills - Obstetrics and Gynecology

Share to:

The premenstrual medication has not been finished, and menstruation has already started?


I have taken the third pack of Misoprostol.
I usually take it at around 3 or 4 PM, but on the day I took the 20th pill, I had to take it at 10 PM instead.
By around midnight, I noticed a small amount of brownish blood.
Should I continue to take the 21st pill? I usually start a new pack on the fifth day of my period, so should I consider the day I noticed the blood as the first day of my period?

1.
Hormonal medications vary in their administration depending on their intended use.
2.
For contraceptive purposes, they can be discontinued after the onset of menstruation.
3.
For the treatment of gynecological conditions, such as endometriosis and menstrual cycle disorders, they should be continued until all medications are completed, even after the onset of menstruation.

More Info


When taking contraceptive pills, particularly combination oral contraceptives like the one you mentioned (美適儂), it's not uncommon to experience some irregular bleeding or spotting, especially when you have missed a dose or taken it later than usual. The situation you described, where you noticed a small amount of brownish discharge after taking your pill later than usual, can be concerning, but it is often not a cause for alarm.

First, let's clarify a few points regarding the use of contraceptive pills and what to do in your situation:
1. Continuing the Pill Pack: Yes, you should continue taking the remaining pills in your current pack. The brownish discharge you observed is likely breakthrough bleeding or spotting, which can occur due to hormonal fluctuations when the timing of your pill intake is altered. This is especially common when you take the pill later than your usual time. It is essential to complete the pack to maintain the effectiveness of the contraceptive and to keep your hormone levels stable.

2. Determining the First Day of Your Period: The first day of your menstrual cycle is typically counted from the first day of full flow (bright red blood), not from spotting or brown discharge. Since you mentioned that the discharge was minimal and brown, it may not be considered the start of your period. Instead, you should continue to monitor your bleeding. If you experience a heavier flow that resembles a typical menstrual period, then you can consider that the first day of your cycle.

3. Understanding Breakthrough Bleeding: Breakthrough bleeding can occur for various reasons, including missed pills, hormonal adjustments, or even stress. If you consistently take your pills as directed, the likelihood of experiencing breakthrough bleeding decreases. However, if this becomes a frequent occurrence, it may be worth discussing with your healthcare provider, as they may consider adjusting your contraceptive method or dosage.

4. Consulting Your Healthcare Provider: If you have any concerns about the bleeding or if it continues beyond a few days, it would be prudent to consult your healthcare provider. They can provide personalized advice based on your medical history and current situation. Additionally, if you experience any severe symptoms such as heavy bleeding, severe pain, or other unusual symptoms, seek medical attention promptly.

5. General Advice on Contraceptive Pills: Always aim to take your contraceptive pill at the same time each day to maintain consistent hormone levels. If you miss a pill or take it late, follow the instructions provided with your medication regarding missed doses. Most contraceptive pill packs include guidelines on what to do in such situations.

In summary, continue taking your contraceptive pills as scheduled, and do not count the brown discharge as the start of your period unless it progresses into a heavier flow. If you have ongoing concerns or if the bleeding persists, reach out to your healthcare provider for further evaluation and guidance.
