Pregnancy Risk After 6 Days of Birth Control Pill Use: What to Know

If the emergency contraceptive pill has not been taken for a full 7 days, and ejaculation occurs inside the body?

Hello doctor, I would like to ask about my situation.
Since this is my first time taking pre-exposure contraceptive pills, I had intercourse 8 hours after taking the sixth pill.
What is the likelihood of pregnancy if I have not taken the pills for a full 7 days? Additionally, would you recommend taking emergency contraception? Thank you.

Hello, the first time you take birth control pills, it is recommended to start on the first day of your menstrual cycle.
If you start taking the pills after the second day of your period, it is advised to use additional contraceptive measures, such as emergency contraception, for the first seven days of taking the pills.
Thank you! Wishing you safety and health.
Dr.

More Info

When it comes to the use of birth control pills and the risk of pregnancy, it's important to understand how these medications work and the timeline for their effectiveness. Birth control pills, particularly combination pills that contain both estrogen and progestin, are designed to prevent ovulation, thicken cervical mucus, and thin the uterine lining to reduce the likelihood of pregnancy.

In your case, since you mentioned that you are on your sixth pill and had unprotected intercourse shortly after taking it, it’s crucial to consider a few factors. Generally, most birth control pills require at least seven consecutive days of use to become fully effective. This means that if you have not taken the pill for a full week, there is a higher risk of ovulation occurring, which could lead to pregnancy if you engage in unprotected sex.

The effectiveness of birth control pills increases significantly after seven days of consistent use. If you had intercourse before reaching this seven-day mark, the chances of becoming pregnant are indeed higher compared to if you had been on the pill for a longer duration.
Regarding your question about taking emergency contraception (often referred to as the "morning-after pill"), it is an option you may consider if you are concerned about the risk of pregnancy. Emergency contraception is most effective when taken as soon as possible after unprotected intercourse, ideally within 72 hours, but some types can be effective up to 5 days afterward. It works primarily by delaying ovulation and is not effective if ovulation has already occurred.

If you decide to take emergency contraception, it is important to follow the instructions provided with the medication and consult with a healthcare provider if you have any concerns or questions about its use. Additionally, it’s advisable to continue taking your birth control pills as prescribed to maintain contraceptive protection moving forward.

In summary, since you are on your sixth pill and had unprotected intercourse, there is a risk of pregnancy. If you are concerned, taking emergency contraception could be a prudent step. Always consult with your healthcare provider for personalized advice, especially when it comes to contraceptive methods and any potential risks associated with them. They can provide you with the most accurate information based on your specific situation and health history.

Hello, doctor: I would like to ask if taking birth control pills on the sixth day after the onset of menstruation still provides contraceptive protection. Additionally, does long-term use of birth control pills affect the likelihood of conceiving in the future?

Dr. Li Guanghan reply Obstetrics and Gynecology
Taking it on the sixth day also has contraceptive effects. Long-term use of exogenous hormones can interfere with the body's hormones and may affect the fertility rate immediately after discontinuation, but normal fertility rates can be restored after a few months.
