Vaginal bleeding


Hello, doctor.
I have been taking the oral contraceptive pill for three months.
Initially, I experienced some spotting, but that stopped.
However, I have noticed some light bleeding from the vagina again over the past few days.
Is this normal, or should I get checked to see if there is an issue with my body?

Hello, you can observe for a while longer.
It is possible that the contraceptive pill you are taking is a low-dose formulation.
If bleeding continues to occur, it is recommended to try a contraceptive pill with a higher dosage.
Wishing you good health.

More Info


Vaginal bleeding can be a concerning symptom, especially when it occurs outside of your regular menstrual cycle. In your case, since you have been taking birth control pills for three months, it's important to understand the potential causes of this bleeding and when to seek medical advice.

Firstly, it is not uncommon for individuals who start taking hormonal contraceptives, such as birth control pills, to experience some irregular bleeding or spotting, especially during the first few months of use. This is often referred to as "breakthrough bleeding." It occurs because the body is adjusting to the new hormone levels introduced by the contraceptive. For many, this irregular bleeding diminishes or resolves after a few cycles as the body adapts.

However, if you are experiencing bleeding that is persistent, heavier than spotting, or accompanied by other symptoms such as pain, discomfort, or unusual discharge, it is advisable to consult a healthcare provider. Other potential causes of vaginal bleeding while on birth control can include:
1. Hormonal Imbalance: Sometimes, the hormones in the birth control pills may not be adequately suppressing ovulation or stabilizing the uterine lining, leading to unexpected bleeding.

2. Infection: Conditions such as pelvic inflammatory disease (PID), bacterial vaginosis, or sexually transmitted infections (STIs) can cause bleeding and should be evaluated by a healthcare professional.

3. Cervical or Uterine Issues: Polyps, fibroids, or other abnormalities in the cervix or uterus can lead to bleeding. These conditions may require further investigation through pelvic exams or imaging studies.

4. Missed Pills: If you have missed any doses of your birth control pills, this can lead to breakthrough bleeding. It is essential to take the pills consistently as directed to maintain hormone levels.

5. Pregnancy: Although unlikely if you are taking your birth control correctly, any unexpected bleeding should prompt a pregnancy test to rule out this possibility.

In summary, while some spotting can be normal when starting birth control, it is crucial to monitor the situation. If the bleeding continues, increases in volume, or is accompanied by other concerning symptoms, you should seek medical advice. A healthcare provider can perform a thorough evaluation, which may include a physical examination, pelvic ultrasound, or lab tests, to determine the underlying cause of your symptoms and recommend appropriate treatment if necessary.

In the meantime, keep track of your bleeding patterns, any additional symptoms, and your medication adherence. This information will be helpful for your healthcare provider in assessing your situation. Remember, it is always better to err on the side of caution when it comes to your health, so do not hesitate to reach out for professional guidance.
