Pregnancy On Birth Control: Is It Possible?

Birth control pills are a popular method of preventing pregnancy. However, they are not 100% effective, and it is possible to get pregnant while taking them. The chances of getting pregnant on the pill depend on several factors, including correct and consistent usage, health conditions, and the use of other medications. Perfect use of birth control pills, which involves taking them at the same time every day, can achieve 99% effectiveness. However, typical use, which includes missing doses or not taking them at the same time each day, lowers the effectiveness to around 91%.

Additionally, certain health conditions and medications can interfere with the effectiveness of birth control pills. For example, vomiting, severe diarrhea, and taking certain antibiotics or supplements can reduce their ability to prevent pregnancy. It is important for individuals to carefully read the information and instructions provided with their chosen method of birth control and consult a healthcare professional if they have any concerns or questions.

Missing a pill

It is important to take your birth control pill every day. However, missing a pill does not guarantee that you will get pregnant. The chance of pregnancy is generally not any higher than usual, except in the case of progesterone-only pills.

If you are taking a combination pill, which contains both estrogen and progestin, and you miss one pill, you can simply take the missed pill as soon as you remember and continue taking the rest of the pills as normal. You do not need to use a backup method of contraception unless you missed a pill during the first week of a new pack, in which case you should use another form of contraception for the next 7 days.

If you are taking a progestin-only pill, or mini-pill, and you are more than 3 hours late in taking it, you will need to use a backup form of contraception for 2 days. If you forgot to take the pill yesterday, take it as soon as you remember, and then take today's pill at the regular time. If you forgot to take the pill for 2 or more days in a row, take the most recent pill you missed, throw away the others, and then continue taking the rest of the pills as normal. However, if you missed pills during the first week of a new pack, you should use a different form of contraception until you have taken your pill every day for 7 days.

If you are unsure about what type of pill you are taking or what to do if you miss a pill, you should consult your doctor or pharmacist.

Taking antibiotics

While it is rare, it is possible to get pregnant while on birth control. This can happen for a variety of reasons, including missing pill days, vomiting, severe diarrhoea, and taking certain medications.

Certain antibiotics can interfere with the effectiveness of birth control pills, patches, shots, implants, or vaginal rings. Rifamycin antibiotics, such as rifampin (also known as Rifadin and Rimactane), are known to lower the effectiveness of hormonal birth control methods. Rifamycins can speed up the rate at which the liver breaks down the hormones in birth control, reducing their effectiveness in preventing pregnancy. If you are taking rifamycins, it is recommended to use a backup birth control method, such as condoms or a diaphragm, for 28 days after finishing the antibiotic course.

Other types of antibiotics, such as quinolones (ciprofloxacin, ofloxacin), do not affect birth control. These antibiotics are commonly used to treat bacterial infections and can be taken without concerns about a higher risk of pregnancy. The same is true for antifungals; most common antifungals, including those used to treat vaginal yeast infections, do not interfere with birth control. However, griseofulvin, an antifungal used for skin and scalp infections, can increase the chances of an unplanned pregnancy if taken with combined birth control pills. In this case, a backup birth control method should be used for a month after the last dose of griseofulvin.

It is important to note that some antibiotics can cause nausea, vomiting, and diarrhoea, which may affect the absorption of hormones in birth control pills. If vomiting or diarrhoea occurs within a few hours of taking the pill, it is recommended to take another pill right away and use a backup method if the symptoms persist for more than a day.

Vomiting or diarrhoea

If you are taking a progestin-only birth control pill, the recommendations are slightly different. If you vomit within 2 hours of taking your pill, take another pill right away. If you do not take a replacement pill within 3 hours of your normal time, use a backup method for the next 48 hours.

If you are experiencing nausea as a side effect of the pill, you may find relief with the following remedies:

• Consume only light, plain foods, such as bread and crackers.
• Avoid any foods that have strong flavours, are very sweet, or are greasy or fried.
• Avoid any activity after eating.
• Drink a cup of ginger tea.
• Eat smaller, more frequent meals.
• Take a series of deep, controlled breaths.
• Apply pressure to certain points on the wrist, a traditional Chinese remedy called acupressure.

If nausea persists, make an appointment to see your doctor. You may need to switch to another type of pill or a different form of birth control.

Not taking pills at the same time each day

Not taking birth control pills at the same time each day can increase the chances of becoming pregnant. This is because birth control pills are designed to maintain a constant level of hormones in the body. Taking the pill at inconsistent times can cause hormone levels to drop, which may trigger ovulation and increase the chances of pregnancy.

To ensure effectiveness, it is recommended that individuals take their birth control pill at the same time every day. Setting reminders or taking the pill during a specific daily activity can help maintain a consistent schedule. Additionally, it is important to follow the instructions provided with the medication and consult a doctor if there are concerns about one's ability to take the pill consistently.

The mini-pill, or progestin-only pill, requires particular attention to timing. If an individual is late by even three hours when taking this type of pill, a backup method of contraception, such as a condom, should be used.

It is worth noting that even with perfect use, no form of birth control is 100% effective at preventing pregnancy. However, taking the pill correctly and consistently can significantly reduce the chances of an unintended pregnancy.

Not starting a new pack right away

Not starting a new pack of birth control pills right away can increase the chances of an accidental pregnancy. It is important to start a new pack of pills the day after finishing the previous one. However, it is not always possible to have a new pack in time. Missing a few days between packs can make the pill less effective in preventing pregnancy.

According to the CDC, if you miss two or more pills in a row, you should use a backup birth control method or avoid sexual intercourse until you have taken the birth control pill for a certain period of time. The CDC recommends using a backup method for the next seven days or avoiding sex.

To prevent this situation, it is recommended that you always get a new pill pack at least one week before the last pill pack is due to run out. This will help you maintain consistent hormone levels and reduce the risk of pregnancy.

Additionally, it is important to remember that birth control pills are not 100% effective, even with perfect use. Other factors such as weight, certain medications, and health conditions can also impact their effectiveness. Therefore, it is crucial to follow the instructions carefully, take the pills at the same time each day, and consider using backup methods or abstaining from sex if you miss a dose or start a new pack late.
