Can I get pregnant?

Hello Doctor, I am currently using the oral contraceptive brand Qlaira for the first time.
I started taking it on March 18, and on March 23, I had unprotected intercourse.
What is the likelihood of pregnancy in this situation? If I experience side effects and want to stop taking the pill, can I just stop it immediately, or do I need to finish the 21 days and then take a 7-day break before stopping? Thank you, Doctor.

Hello Ms.
Zhu: Theoretically, if you are taking oral contraceptives consistently every day without interruption, you do not need to worry about the possibility of pregnancy, and there is no need to use condoms additionally.
The failure rate of oral contraceptives is the lowest among all contraceptive methods.
However, it is still important to monitor whether your period arrives; if it does not, you should take a pregnancy test.
If you wish to stop taking the contraceptive due to side effects, you can do so immediately, but be prepared for the possibility of temporary menstrual irregularities.
If the side effects are not too severe and you want to avoid menstrual disturbances, you may choose to wait until you finish the 21-day course before discontinuing the medication.

More Info

When it comes to the question of whether you can get pregnant while on birth control, particularly with oral contraceptives like the one you mentioned (Qiliana), it’s essential to understand how these medications work and the factors that can influence their effectiveness.

Oral contraceptives are designed to prevent ovulation, which means that if taken correctly, they significantly reduce the chances of becoming pregnant. The effectiveness of birth control pills is contingent upon consistent and correct usage. For most combination birth control pills, including Qiliana, it is recommended to take the pill at the same time every day. If you start taking the pill on the first day of your menstrual cycle, you are protected from pregnancy immediately. However, if you start taking the pill at any other time during your cycle, it typically takes about seven days of consistent use before you are fully protected against pregnancy.

In your case, since you started taking the pill on March 18 and had unprotected intercourse on March 23, you were still within the initial week of starting the pill. Therefore, you may not have been fully protected against pregnancy during that time, which could increase your risk of conception. It’s important to note that the risk is not absolute; while the chances of getting pregnant are higher when pills are not taken correctly, they are still relatively low compared to not using any form of contraception at all.

If you experience side effects from the pill and decide to stop taking it, you can generally stop at any time. There is no need to finish the entire pack or wait for the seven-day break. However, it’s advisable to consult with your healthcare provider before making any changes to your birth control regimen. They can provide guidance based on your specific health needs and help you explore alternative contraceptive methods if necessary.

Additionally, if you are concerned about the possibility of pregnancy after unprotected intercourse while on the pill, you might consider taking a home pregnancy test if your period is late or if you experience any unusual symptoms. If you have further concerns or questions about your contraceptive options or potential pregnancy, it’s best to reach out to your healthcare provider for personalized advice.

In summary, while oral contraceptives like Qiliana are effective at preventing pregnancy when used correctly, starting the pill does require a few days of consistent use for full protection. If you have unprotected intercourse shortly after starting the pill, there is a risk of pregnancy. If you decide to stop taking the pill due to side effects, you can do so immediately, but consulting with a healthcare professional is always a good practice to ensure you have the best contraceptive plan for your needs.
