When taking a 21-day oral contraceptive pill, your next menstrual period typically occurs during the placebo week, which is usually the week after you finish the 21 active pills. If you finish the active pills on a Sunday, for example, you can expect
Hello, doctor.
My period started on November 6th, and my period tracking app predicts my next period will be from December 6th to December 13th.
I will be going abroad to soak in a hot spring from December 2nd to 5th, and I have a wedding photoshoot on December 20th.
I would like to avoid having my period during these two periods.
This is my first time taking oral contraceptives, and I am concerned that if I start taking the first pill today, November 7th, my next period might come earlier.
Could you please advise me on which day of my cycle I should start taking the pills to ensure my period occurs between December 6th and 19th?

Hello, you started taking birth control pills on November 12th, and your period is expected around December 6th.
Since you started the pills later, the contraceptive effectiveness may be reduced, so it's advisable to use condoms for additional protection.
Wishing you good health.

When it comes to timing your menstrual cycle with birth control pills, it's important to understand how these medications work and how they can influence your cycle. Birth control pills are designed to regulate your hormones and can help you manage your menstrual cycle effectively.
Typically, birth control pills come in a 28-day pack, with 21 active pills containing hormones and 7 inactive pills (placebo) that do not contain hormones. When you take the active pills, they prevent ovulation and help regulate your menstrual cycle. The withdrawal bleed (similar to a period) usually occurs during the week you take the placebo pills.
In your case, since you are starting the birth control pill on November 7, you will need to consider how the timing of your pill intake will affect your cycle. If you start taking the pill on November 7, you will likely experience your withdrawal bleed during the placebo week, which would be around the first week of December, depending on the specific pill regimen you are following.
To avoid having your period during your planned activities (the hot springs trip from December 2-5 and the wedding photoshoot on December 20), you can manipulate your cycle by skipping the placebo pills. Here’s how you can do it:
1. Start Taking the Pills: Begin taking the active pills on November 7 as planned.
2. Skip the Placebo Pills: Instead of taking the placebo pills in the last week of your pack, continue taking the active pills from the next pack. This will delay your withdrawal bleed, allowing you to avoid your period during your trip and photoshoot.
3. Plan Ahead: If you want your period to occur after December 20, you can then take the placebo pills from the second pack after your wedding photoshoot, which should allow your period to come in the following week.
It's crucial to note that while this method is generally effective, individual responses to birth control pills can vary. Some women may experience breakthrough bleeding or spotting when they skip the placebo pills, so it's a good idea to have a backup plan just in case.
Additionally, if you have any underlying health conditions or are taking other medications, it’s advisable to consult with your healthcare provider before making any changes to your birth control regimen. They can provide personalized advice based on your health history and ensure that you are using the pills safely and effectively.
In summary, by starting your birth control pills on November 7 and skipping the placebo pills, you can effectively time your menstrual cycle to avoid having your period during your planned events. Always remember to consult with your healthcare provider for tailored advice and to address any concerns you may have regarding your birth control method.
