Missed two days of birth control pills and experienced bleeding?


Hello, the patient has been taking the contraceptive pill (21-day pack) for over a year.
This time, she started her menstrual period on March 16 and began taking the first pill on the fifth day, March 20.
However, she forgot to take the pills on April 2 and 3, and on April 4, she took three pills at once.
Later that evening, she noticed what seemed to be menstrual bleeding, even though she had previously missed two pills without experiencing sudden bleeding.
She is unsure whether this is menstrual bleeding, irregular bleeding, or breakthrough bleeding due to pregnancy.
If it is menstrual bleeding, can the remaining five pills be saved for later use? Also, will taking the three pills at once have any effects? If she is waiting for her period, should she continue taking the pills on the fifth day?

Just monitor the situation, but you should take additional contraceptive measures.

More Info


When it comes to missed birth control pills, breakthrough bleeding can often be a concern for many women. In your case, it seems that you have been taking a combination oral contraceptive pill (OCP) for over a year, and you recently experienced some irregular bleeding after missing a couple of pills. Let’s break down what might be happening and what steps you can take next.

First, it’s important to understand that missing birth control pills can lead to hormonal fluctuations in your body. The primary function of OCPs is to maintain stable hormone levels to prevent ovulation and regulate your menstrual cycle. When you miss pills, especially two in a row, your hormone levels can drop, which may trigger withdrawal bleeding. This bleeding can resemble a menstrual period but is often lighter and shorter in duration.

In your situation, since you missed two pills on April 2nd and 3rd and then took three pills on April 4th, it’s likely that the bleeding you observed could be breakthrough bleeding rather than a full menstrual period. Breakthrough bleeding is common when pills are missed, and it does not necessarily indicate that you are pregnant. However, it is essential to consider the possibility of pregnancy, especially if you had unprotected intercourse during the time you missed your pills.

If you suspect that the bleeding is indeed your period, you can continue taking the remaining pills as scheduled. However, if you are unsure whether it is a period or breakthrough bleeding, it’s advisable to take a pregnancy test if your next period is late or if you have any other symptoms of pregnancy, such as nausea or breast tenderness.

Regarding the pills you took on April 4th, taking three pills at once is not recommended as it can lead to increased side effects such as nausea or vomiting. It’s best to take the pills as directed, which usually means one pill per day. If you have already taken the three pills, monitor how you feel, and if you experience any adverse effects, consult your healthcare provider.

As for your question about continuing the remaining five pills, if you determine that the bleeding is not a full period and you are not pregnant, you can continue taking the pills as usual. If the bleeding persists or if you have any concerns about your menstrual cycle or potential pregnancy, it’s a good idea to consult with your healthcare provider for personalized advice.

In summary, missed pills can lead to breakthrough bleeding, and while it can be concerning, it is often a temporary issue. Always keep track of your pill-taking schedule, and if you miss pills, follow the instructions provided with your medication or consult your healthcare provider for guidance. If you have any doubts about your bleeding or potential pregnancy, taking a pregnancy test and discussing your situation with a healthcare professional is the best course of action.
