Emergency contraception pills + menstrual issues
Hello, doctor.
I have been taking oral contraceptives for over two years, specifically the brand Aisle.
Around July, I started taking weight loss pills, which seemed to cause some menstrual irregularities, but it appeared to have returned to normal afterward.
Here are my menstrual dates: July 12-15, August 6-7, August 31-September 4, and October 24-27.
I received the first dose of the nine-valent HPV vaccine on October 23, and I have not had my period since November.
I took the contraceptive pills from November 1-14, but I lost the pills and stopped taking them on the 15th.
On the 25th, I noticed brownish discharge, which I thought was my period, so I resumed taking the pills (I have been taking the new pack from the 25th until now).
I have been experiencing premenstrual symptoms, such as acne and lower back pain, for the past three days, and there has been increased discharge.
Q1: If I have been taking the contraceptive pills since the 25th, should I continue taking them or wait for my period to start again? (The pharmacist said to take them on the first day of my period.)
Q2: I had unprotected intercourse with withdrawal on the 15th, and I tested negative for pregnancy on November 30.
Is this simply a case of menstrual irregularity?
Q3: Should I take medication to induce my period? I am concerned that my menstrual cycle may become more irregular.
Q4: Is it possible that the nine-valent vaccine has caused my menstrual irregularities?

Hello, if you finish taking the birth control pills and start again on the fifth day after your period begins, it is likely that you are not pregnant.
Wishing you good health.

More Info
Understanding birth control pills and menstrual irregularities can be quite complex, especially when various factors come into play, such as weight loss medications and vaccinations. Let's break down your questions and concerns regarding your menstrual cycle and the use of birth control pills.
Q1: Should I continue taking the birth control pills after starting on the 25th, or wait for my period to begin?
When you are on birth control pills, it is generally recommended to take them continuously as prescribed, regardless of whether you are experiencing bleeding or spotting. If you started a new pack on the 25th and have been taking them consistently, you should continue taking them as directed. Birth control pills work best when taken at the same time every day, and stopping them can lead to further irregularities in your cycle. The advice you received about starting the pill on the first day of your period is typically for those who are beginning the pill for the first time. Since you are already on the pill, continue taking it until the end of the pack.
Q2: Is it possible that the irregularities are just a result of my menstrual cycle being disrupted?
Yes, it is quite possible that your menstrual irregularities are due to a combination of factors, including the use of weight loss medications and the stress of potential pregnancy. The fact that you had unprotected intercourse on the 15th and tested negative for pregnancy on the 30th is reassuring, but it is important to remember that hormonal fluctuations can cause changes in your cycle. Stress, changes in weight, and even the introduction of new medications can all contribute to irregular periods.
Q3: Should I take medication to induce my period?
It is generally not advisable to take medication to induce your period without consulting a healthcare provider. Inducing your period can lead to further hormonal imbalances and may not address the underlying issue causing your irregular cycles. If your period does not return to normal in the next few cycles, or if you continue to experience significant irregularities, it would be wise to consult with your healthcare provider for a thorough evaluation.
Q4: Could the HPV vaccine (Gardasil 9) be causing my menstrual irregularities?
While some individuals report changes in their menstrual cycle after receiving the HPV vaccine, scientific evidence linking the vaccine to menstrual irregularities is limited. The HPV vaccine is generally considered safe and effective, and any changes in your cycle could be attributed to other factors, such as stress, weight changes, or the use of other medications. If you suspect that the vaccine may be affecting your cycle, it is best to discuss this with your healthcare provider.
In summary, it is important to maintain a consistent regimen with your birth control pills and to monitor your menstrual cycle for any significant changes. If irregularities persist or worsen, seeking advice from a healthcare provider is crucial. They can provide personalized recommendations based on your medical history and current situation. Remember, your health and well-being are paramount, and open communication with your healthcare provider will help you navigate these concerns effectively.
