Can you get pregnant while taking birth control pills?


Hello Doctor: On the fifth day of my menstrual period on October 2, I had unprotected intercourse and started taking Diane contraceptive pills that evening.
I have been taking them regularly every day since then.
Is there still a possibility of pregnancy? My menstrual cycle is approximately 35 days.
On the evening of October 13, I suddenly felt nauseous, and in the past few days, I have also experienced sudden hot flashes followed by chills.
I have a habit of tracking my basal body temperature, and since I started taking the contraceptive pills, my temperature has consistently been around 36.69°C.
Does this mean that my body temperature is no longer a reliable indicator due to the contraceptive pills? I am very worried about being pregnant, so I took a urine pregnancy test on the morning of October 14, which showed one line.
Should I take another test in a few days?

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; approximately the same time is sufficient.
As long as you take it regularly, it will be effective for contraception.
If a urine pregnancy test shows one line, it indicates that you are likely not pregnant.
Wishing you good health!

When it comes to the question of whether you can get pregnant while taking birth control pills, the short answer is that it is highly unlikely if the pills are taken correctly. Birth control pills, such as the one you mentioned (Diane), are designed to prevent ovulation, which means that if taken consistently and correctly, they are very effective at preventing pregnancy.

In your case, you started taking the birth control pill on the fifth day of your menstrual cycle, which is generally considered a safe time to begin taking the pill, especially if you are using a combination pill. The first seven days of taking the pill are often referred to as a "grace period," during which you should use an additional form of contraception (like condoms) if you have unprotected intercourse. Since you had unprotected intercourse on the fifth day of your cycle and began taking the pill that same day, it is possible that you may have been protected, but it is not guaranteed until you have taken the pill for at least seven consecutive days.

Regarding your symptoms of nausea, sweating, and temperature fluctuations, these could be side effects of starting the birth control pill. Hormonal contraceptives can cause various side effects as your body adjusts to the new hormone levels. However, it is important to note that these symptoms can also be indicative of early pregnancy, especially if they are accompanied by a missed period or other pregnancy-related signs.

You mentioned that you took a pregnancy test on October 14 and received a negative result (one line). This is a good indication that you are not pregnant, especially since it was taken relatively soon after intercourse. However, if you are still concerned about the possibility of pregnancy, it is advisable to wait a few days and take another test. Pregnancy tests are most accurate when taken after a missed period, as this allows enough time for the hormone hCG (human chorionic gonadotropin) to build up in your system if you are pregnant.

As for your basal body temperature, it is true that hormonal contraceptives can affect your temperature readings. The consistent high temperature you are observing (36.69°C) may not be a reliable indicator of ovulation or pregnancy while you are on the pill. Birth control pills work by maintaining stable hormone levels, which can prevent the typical fluctuations in basal body temperature that occur during a natural menstrual cycle.

In summary, while it is unlikely that you are pregnant if you have been taking your birth control pills correctly, it is always wise to monitor your body and consult with a healthcare provider if you have concerns. If you continue to experience unusual symptoms or if your period does not arrive as expected, seeking medical advice is recommended. Additionally, if you have any doubts about the effectiveness of your birth control method or if you experience any side effects that concern you, discussing these with your healthcare provider can provide clarity and peace of mind.
