Taking pre-exposure prophylaxis (PrEP) did not stop the menstrual period?
I have never taken preemptive medication before.
I had a uterine fibroid removal surgery last August.
My menstrual cycle used to be 28-34 days, lasting about 5-7 days.
Starting in July, I wanted to use preemptive contraception and began taking 28 tablets of Yaz at the start of my period.
According to my doctor and pharmacist, I was advised to start taking it at the beginning of my menstrual cycle.
On July 24, I experienced a small amount of brown discharge, and on July 25, I had a small amount of red bleeding (when I started taking Yaz).
The bleeding significantly decreased only after 11 days, on August 3, but I continued to have daily light red bleeding with small blood clots (it was not enough to overflow onto my outer clothing) until August 9, and the bleeding has not stopped.
I have been taking the medication consistently every day.
I would like to ask the doctor: 1.
Does having uterine fibroids affect the medication? 2.
I read that changes may occur within three months of starting the medication due to hormonal effects, and I would like to know if I should continue taking it for three months and then reassess (continuing for three cycles)? 3.
Is my persistent bleeding considered normal, or should I seek medical attention? 4.
Is this level of bleeding what is referred to as spotting? 5.
Given that I am still experiencing bleeding, is it safe to have sexual intercourse? Will it still provide contraceptive protection?

Hello, the user: During the use of contraceptive pills, if menstruation or breakthrough bleeding occurs, there is no need to stop taking the medication; continue to take it as scheduled.
Once the body adjusts to the contraceptive pills, abnormal bleeding should cease.
However, if irregular bleeding persists for more than three months or if there is heavy bleeding, it is advisable to consult a physician.
The likelihood of fibroids affecting the efficacy of contraceptive pills is low.
Combined oral contraceptives (COCs) must be taken at the same time every day; correct usage can achieve a 99% effectiveness rate in preventing pregnancy.
Thank you! Wishing you peace and health, Dr.
Zhang.

More Info
Prolonged bleeding while taking birth control pills can be a concerning issue for many women, especially those who have undergone previous surgeries like myomectomy for uterine fibroids. Let's address your questions one by one, while also providing some context and additional information regarding the use of hormonal contraceptives and their effects on menstrual cycles.
1. Impact of Uterine Fibroids on Medication: Uterine fibroids can influence menstrual bleeding patterns, and their presence may affect how your body responds to hormonal contraceptives. Fibroids can cause heavier menstrual bleeding and prolonged periods, which might be exacerbated when starting birth control pills. While the pills are designed to regulate your cycle and reduce bleeding, the underlying condition of fibroids can sometimes lead to unexpected bleeding patterns, including breakthrough bleeding or prolonged spotting.
2. Hormonal Changes in the First Three Months: It is common for women to experience irregular bleeding or spotting during the first few months of starting a new birth control regimen. This is often due to the body adjusting to the new hormone levels. Many healthcare providers recommend continuing the pills for at least three months to allow your body to adapt. If the bleeding persists beyond this period or becomes excessively heavy, it would be advisable to consult your healthcare provider for further evaluation.
3. Normalcy of Prolonged Bleeding: Continuous bleeding for an extended period, such as the 11 days you mentioned, is not typical and should be evaluated. While some spotting can be normal, especially in the initial months of starting birth control, persistent bleeding may indicate that the contraceptive method is not suitable for you or that there may be other underlying issues that need to be addressed.
4. Understanding Spotting: The term "spotting" typically refers to light bleeding that occurs outside of your regular menstrual period. If you are experiencing small amounts of red blood and clots, this could be classified as spotting or breakthrough bleeding. However, the distinction between spotting and a heavier flow can sometimes be subjective and depends on the amount and duration of the bleeding.
5. Sexual Activity During Bleeding: Engaging in sexual intercourse while experiencing bleeding is generally safe, but it is important to consider personal comfort and hygiene. As for contraceptive effectiveness, if you have been taking your birth control pills consistently and correctly, they should still provide effective contraception, even if you are experiencing breakthrough bleeding. However, if you are concerned about the bleeding or its implications, discussing this with your healthcare provider is wise.
Additional Considerations
- Consultation with a Healthcare Provider: Given your history of uterine fibroids and the current prolonged bleeding, it is crucial to keep an open line of communication with your healthcare provider. They may want to perform an examination or imaging studies to ensure there are no complications related to the fibroids or the birth control method you are using.
- Alternative Contraceptive Options: If the current birth control method continues to cause issues, your doctor may suggest alternative contraceptive options, such as a different type of hormonal pill, an intrauterine device (IUD), or non-hormonal methods. Each option has its own set of benefits and potential side effects, which should be discussed thoroughly.
- Monitoring Symptoms: Keep a detailed record of your bleeding patterns, including the amount, duration, and any associated symptoms (such as pain or discomfort). This information can be invaluable for your healthcare provider in determining the best course of action.
In conclusion, while some irregular bleeding can be expected when starting birth control pills, prolonged or heavy bleeding warrants further investigation. Your health and comfort are paramount, so do not hesitate to reach out to your healthcare provider for guidance tailored to your specific situation.
