Contraceptive pill issues?


Doctor, I would like to ask a question.
I am the person who asked about issue 209701.
After our last discussion, I finished taking my birth control pills and started taking the iron supplements included with the pills on July 13.
Less than two days later, on the evening of July 15, it seemed like my period started, but the blood flow was very light, less than half a pad, and it appeared brown when I wiped.
On July 17, it turned bright red, but the flow was still minimal.
On July 18, it was brown again with little volume.
Is this normal, or could it be that my period hasn’t fully cleared out? I would also like to ask if this is considered my period?

More Info


Irregular menstrual bleeding after the use of birth control can be a common concern for many women. In your case, it sounds like you have recently stopped taking birth control pills and have started taking iron supplements, which may have influenced your menstrual cycle. Let’s break down your situation and address your questions.

1. Understanding Menstrual Changes After Birth Control: When you stop taking hormonal birth control, your body may take some time to readjust to its natural hormonal cycle. This can lead to irregular bleeding or spotting, which may not resemble your typical menstrual period. The bleeding you experienced shortly after stopping the pills could be a withdrawal bleed, which is common as your body responds to the sudden change in hormone levels.

2. Color and Flow of Menstrual Blood: The color of menstrual blood can vary throughout your cycle. Fresh red blood typically indicates a more recent flow, while brown or coffee-colored blood often signifies older blood that has taken longer to exit the uterus. The fact that you experienced a mix of colors and a light flow could suggest that your body is still adjusting. It’s not unusual for the first few cycles after stopping birth control to be lighter or irregular.

3. Duration and Amount of Bleeding: The amount of bleeding you described—less than half a pad and varying in color—can be considered normal for someone who has recently stopped hormonal contraception. It’s possible that your body is still clearing out the lining of the uterus, especially if you had not had a period for a while due to the birth control.

4. Is This a Menstrual Period?: Given the timeline and the nature of the bleeding, it could be considered a menstrual period, albeit an irregular one. If you have not had a regular cycle for some time, it may take a few months for your periods to normalize. Keep in mind that every woman's body reacts differently, and it may take time for your menstrual cycle to stabilize.

5. When to Seek Medical Advice: If you continue to experience irregular bleeding, or if you have any concerns such as heavy bleeding, severe pain, or any other unusual symptoms, it is advisable to consult with a healthcare provider. They can perform a thorough evaluation to rule out any underlying conditions and provide guidance tailored to your specific situation.

6. Lifestyle Considerations: Maintaining a healthy lifestyle can also help regulate your menstrual cycle. This includes a balanced diet, regular exercise, and managing stress levels. If you are taking iron supplements due to heavy menstrual bleeding or anemia, ensure you are following your healthcare provider's recommendations regarding dosage and duration.

In summary, the irregular bleeding you are experiencing after stopping birth control is likely a normal part of your body readjusting to its natural hormonal rhythm. However, if you have ongoing concerns or if your symptoms change, it’s important to reach out to a healthcare professional for personalized advice and support.
