Consequences of Birth Control Pills


Dear Doctor: I have been taking birth control pills for over two years continuously.
A previous physician advised me to stop for six months before resuming, so I stopped taking the pills after my last menstrual period on May 4.
Now, I have not had my period, which was due on June 12, and I am worried that if I am pregnant, it might affect the baby.
Additionally, my menstrual cycle is irregular, and I experience premenstrual syndrome (PMS), which is why my doctor recommended birth control pills for treatment and contraception.
However, I suffer from severe headaches two days before my period, which is very distressing.
Are there any effective ways to alleviate this? Also, will taking birth control pills continuously have any impact on my health? Thank you for your help, Doctor! I really appreciate it!

Dr. Zhuang Zhijian reply Obstetrics and Gynecology


Hello Miss Hsiao-Ning: Thank you for your inquiry.
I would like to respond to your question and provide some advice: If you are pregnant, the BABP (Birth Control Pill) will not be affected.
I recommend that you relax and rest, as prolonged use of contraception is not appropriate and can lead to irregular menstrual cycles.
Irregularity is not a concern, and there is no need to use birth control pills for treatment.

Understanding the effects of birth control pills on women's health is a multifaceted topic that encompasses various aspects, including hormonal balance, menstrual cycle regulation, and potential side effects. In your case, having taken birth control pills continuously for over two years and then stopping them can lead to several physiological changes, particularly concerning your menstrual cycle and overall reproductive health.

Firstly, it is essential to understand that birth control pills primarily work by regulating hormones in the body. They contain synthetic forms of estrogen and progesterone, which help to prevent ovulation, thicken cervical mucus, and thin the uterine lining. When you stop taking these pills, your body may take some time to readjust to its natural hormonal rhythm. This adjustment period can lead to irregularities in your menstrual cycle, including delayed periods, which seems to be your current experience.
In your situation, since you stopped taking the pills after your last period on May 4th and have not had a period by June 12th, it is not uncommon. Many women experience a delay in their menstrual cycle after discontinuing birth control, especially if they had irregular cycles before starting the pills. The hormonal fluctuations can cause your body to take longer to resume its natural cycle.
Regarding your concern about pregnancy, if you have had unprotected intercourse after stopping the birth control pills, there is a possibility of pregnancy. However, if you are indeed pregnant, it is important to note that the use of birth control pills prior to conception does not typically harm the developing fetus. Most studies indicate that any potential risks are minimal, especially if the pills were discontinued before conception.
You also mentioned experiencing severe headaches and premenstrual syndrome (PMS) symptoms, which can be exacerbated by hormonal fluctuations. If you find that your headaches are particularly debilitating, it may be worth discussing this with your healthcare provider. They might suggest alternative treatments for PMS or recommend lifestyle changes that could help alleviate your symptoms. Some women find relief through dietary adjustments, regular exercise, stress management techniques, or even supplements like magnesium or vitamin B6, which have been shown to help with PMS symptoms.

As for the long-term use of birth control pills, while they are generally safe for most women, there can be side effects. Some women may experience weight gain, mood changes, or increased risk of certain health issues, such as blood clots, especially if they smoke or have other risk factors. However, for many women, the benefits of using birth control pills—such as reduced menstrual cramps, lighter periods, and regulated cycles—outweigh the risks. It is crucial to have regular check-ups with your healthcare provider to monitor your health and discuss any concerns you may have.

In conclusion, if you are experiencing significant anxiety about your menstrual cycle and potential pregnancy, it may be beneficial to take a pregnancy test and consult with your healthcare provider. They can provide personalized advice based on your medical history and current health status. Additionally, if you continue to have irregular cycles or severe PMS symptoms, seeking further evaluation may be warranted to explore other treatment options. Remember, open communication with your healthcare provider is key to managing your reproductive health effectively.
