When taken correctly, birth control pills are one of the most effective methods of contraception available. The typical effectiveness rate for combination oral contraceptives is about 99%, meaning that fewer than 1 in 100 women will become pregnant in a year of consistent and correct use. However, it is important to note that no contraceptive method is 100% effective, and there are several factors that can contribute to the possibility of becoming pregnant while on the pill.

Firstly, the effectiveness of birth control pills can be compromised if they are not taken as directed. Missing a pill, taking them at irregular times, or not starting a new pack on schedule can all increase the risk of ovulation. Additionally, certain medications, such as some antibiotics and anticonvulsants, can interfere with the effectiveness of birth control pills. Therefore, it is crucial to consult with a healthcare provider about any medications you are taking while on the pill.

If a woman does become pregnant while taking birth control pills, she may experience what is known as "withdrawal bleeding," which can sometimes be mistaken for a regular menstrual period. This bleeding occurs due to the sudden drop in hormones when the pill is missed or stopped. However, it is important to recognize that withdrawal bleeding does not indicate a healthy pregnancy. In fact, if a woman suspects she might be pregnant while on the pill, she should take a pregnancy test and consult her healthcare provider for further evaluation.

In terms of symptoms, early pregnancy can present with various signs, which may include:
1. Missed Period: This is often the first indication of pregnancy, but it can be complicated by the use of birth control pills, which can sometimes cause irregular bleeding or missed periods even when not pregnant.

2. Nausea and Vomiting: Commonly referred to as "morning sickness," this can occur at any time of day and typically starts around the sixth week of pregnancy.

3. Breast Changes: Tenderness, swelling, or changes in the nipples can occur due to hormonal changes.

4. Fatigue: Increased levels of progesterone can lead to feelings of tiredness.

5. Frequent Urination: As the pregnancy progresses, hormonal changes and the growing uterus can put pressure on the bladder.

6. Mood Swings: Hormonal fluctuations can lead to emotional changes.

If a woman experiences any of these symptoms while on birth control pills, it is advisable to take a home pregnancy test and consult a healthcare provider for confirmation and guidance.
In conclusion, while the regular and correct use of birth control pills significantly reduces the likelihood of pregnancy, it is not infallible. If pregnancy occurs, it is essential to seek medical advice to ensure proper care and address any concerns regarding the health of both the mother and the developing fetus.
