Birth Control Pills: Common Questions and Concerns

I'm a bit confused about how to take birth control pills?

I have previously read Dr.
Lin's responses to many questions regarding contraceptive pills, as I am also someone who has just started taking them.
However, there are a few things I am unclear about.
Dr.
Lin mentioned that "as long as you start taking the pills from the 5th day of each cycle and continue, there will be a suppressive effect." In my case, I did not start taking the pills on the 5th day of my second cycle because my first cycle ended with my period starting on the last day (the 21st day) before I finished the pills.
Now, in my second cycle, I started taking the pills on the 8th day of my period (the 29th day) because I had to wait 7 days in between.
Is this the correct way to take the medication, Dr.
Lin? Is it normal for my period to start before I finished the first cycle of pills? Should I continue taking the pills for the next cycle regardless of whether my period has just started, just ended, or is still ongoing, as long as the 7-day break has passed?
Another point is that after starting the contraceptive pills, I noticed that my menstrual flow has decreased.
I understand this is normal; however, my first cycle lasted a full 7 days, which is about 2 days longer than my periods before taking the pills (the flow was lighter but the duration was longer).
Is this normal? Shouldn't the duration of my period shorten after starting the medication? I apologize for asking so many complex questions, and I hope Dr.
Lin can take the time to respond.
Thank you.

1.
The middle 7 days are placebo, so you can skip taking them; you should continue taking the pills on the 5th day of your menstrual cycle.
2.
It is normal to experience breakthrough bleeding when you first start taking the medication, as your body may not have fully adjusted yet.
3.
If your period starts early, you can stop taking the pills and begin the next pack directly on the 5th day.
4.
A longer menstrual period is just an adjustment phase; however, if this persists into the second month, you should consult a gynecologist.

Understanding birth control pills can indeed be complex, and it's great that you're seeking clarification on your concerns. Let's address your questions step by step.

1. Starting the Pill: It is generally recommended to start taking birth control pills at the beginning of your menstrual cycle, specifically on the first day of your period or the first Sunday after your period starts. However, if you start taking the pill after your period has begun, such as on the 5th or 8th day, it can still be effective, but it may take a few days for the hormones to build up in your system. If you start taking the pill after your period has begun, it is advisable to use a backup method of contraception (like condoms) for the first seven days of taking the pill to ensure you are fully protected against pregnancy.

2. Missed Days and Timing: If your first cycle ended and your period started before you finished the pack, this can happen and is generally normal. The key point is that after the seven-day break (the placebo week), you should start your next pack regardless of whether your period has ended or not. The hormonal pills are designed to maintain a consistent level of hormones in your body, and the seven-day break is intended to allow for a withdrawal bleed, which is similar to a period.

3. Changes in Menstrual Cycle: It is common for women to experience changes in their menstrual cycle when they start taking birth control pills. Some may find that their periods become lighter and shorter, while others may experience longer periods with lighter flow. The hormonal changes can affect each person differently. If you experienced a longer period during your first cycle on the pill, it could be due to your body adjusting to the hormones. Over time, many women find that their periods become more regular and lighter.

4. Normalcy of Symptoms: The symptoms you are experiencing, such as changes in the duration and flow of your menstrual cycle, are generally considered normal when starting birth control pills. However, if you find that your periods remain unusually long or heavy, or if you experience any other concerning symptoms (like severe pain or unusual discharge), it is important to consult with your healthcare provider. They can assess whether your current birth control method is suitable for you or if adjustments are necessary.

5. Communication with Your Doctor: It’s always a good idea to maintain open communication with your healthcare provider about any concerns or side effects you experience while on birth control pills. They can provide personalized advice based on your medical history and current health status.

In summary, your approach to starting the pill seems reasonable, but remember to use backup contraception initially if you start after your period has begun. Changes in your menstrual cycle are common, and while some variations are normal, keep an eye on any significant changes and discuss them with your doctor. Birth control pills can take a few cycles for your body to adjust, so patience is key. Always feel free to reach out to your healthcare provider for any questions or concerns you may have regarding your birth control method.
