Pre-Conception Pills: Pregnancy Risks and Concerns

Emergency contraceptive pill

Hello Doctor: My girlfriend started taking the emergency contraceptive pill a few days ago.
She took her first pill on the fifth day of her menstrual cycle around 10:30 PM and has been taking it consistently without missing any doses.
However, on the eighth day before taking her pill, there was one instance of ejaculation inside her.
What are the chances of her getting pregnant? I previously called the obstetrics and gynecology department to inquire about the medication, and the nurse said not to worry, but my girlfriend is still feeling anxious (as she is approaching her ovulation period), so I am reaching out to you for advice.

Hello, you can start taking the contraceptive pill on the fifth day of your menstrual period.
It doesn't have to be taken at the exact same time; a general timeframe is sufficient.
As long as you take it regularly, it will be effective for contraception.
Wishing you good health!

When it comes to understanding the risks and concerns associated with pre-conception pills, particularly hormonal contraceptives, it is essential to clarify how they work and their effectiveness in preventing pregnancy. Your girlfriend has started taking birth control pills, which are designed to prevent ovulation, thicken cervical mucus, and thin the uterine lining, making it less likely for a fertilized egg to implant.

In your case, your girlfriend began taking the pill on the fifth day of her menstrual cycle, which is generally considered safe, as long as she continues to take it consistently and correctly. The effectiveness of birth control pills is significantly increased when taken at the same time every day without missing doses. Most combination birth control pills become effective after seven consecutive days of use, but if she started taking the pill on the fifth day of her cycle, she may already be protected from pregnancy, depending on her individual cycle and the specific pill formulation.

Regarding the incident of unprotected intercourse (internal ejaculation) on the eighth day before she took her pill, the risk of pregnancy is relatively low if she has been taking her pills consistently. However, since this occurred close to her ovulation period, there is still a small chance of pregnancy. If she is concerned about this risk, she might consider using emergency contraception, which is most effective when taken as soon as possible after unprotected intercourse.

It is also important to note that hormonal contraceptives can have side effects and may not be suitable for everyone. Some women may experience mood changes, nausea, or other side effects when starting the pill. If your girlfriend has any concerns about her health or the side effects of the pill, she should consult her healthcare provider for personalized advice.

In summary, while the risk of pregnancy is low if the pill is taken correctly, there is still a slight chance, especially if the timing is close to ovulation. If your girlfriend is feeling anxious about the situation, it may be helpful for her to speak with her healthcare provider for reassurance and to discuss any further steps she may want to take. Additionally, understanding the nature of her menstrual cycle and how the pill interacts with it can provide her with more confidence in her contraceptive method.

Please choose a lower dose contraceptive pill. A triphasic pill is preferable, and it is best to take it for six months followed by a one-month break (to reduce excessive suppression of ovulation during the medication break).
