Knowledge related to contraception?


Hello Dr.
Dong: I often see many discussions online regarding contraception, but many still leave me with unanswered questions or doubts, so I decided to consult an expert for more reliable information.
I would like to ask: 1.
If I engage in sexual intercourse with my girlfriend, what are the chances of pregnancy without using a condom compared to using one? 2.
Additionally, do oral contraceptives have any negative health effects on women, and what is the success rate of preventing pregnancy with them? 3.
If a pregnancy test shows a positive result, what are the appropriate steps to take at that point? I would appreciate your answers, doctor.

Hello: It is not advisable to engage in sexual activity too early, especially if one is not capable of taking responsibility for their actions (responsibility encompasses more than just dealing with pregnancy and potential abortion).
Using oral contraceptives or condoms are both viable methods of contraception, but if you wish to avoid unintended pregnancy, it is important to be aware of the correct usage of birth control pills and condoms.
In simple terms, missing a dose of the pill or not using condoms consistently increases the risk of unintended pregnancy.
There is a wealth of information available online, and it is recommended to refer to resources from government health agencies.
If you experience any physical discomfort, seek medical attention promptly.
Thank you.

Understanding contraception is crucial for anyone who is sexually active, and it's great that you're seeking reliable information. Let's address your questions one by one.

1. Pregnancy Chances with and without Condoms: The likelihood of pregnancy varies significantly depending on whether or not a condom is used. When condoms are used correctly and consistently, they are about 98% effective at preventing pregnancy. This means that out of 100 couples using condoms as their only form of birth control for a year, about 2 will experience an unintended pregnancy. On the other hand, when no contraception is used, the average chance of pregnancy is about 85% over the course of a year. This means that if you have unprotected sex, there is a substantial risk of pregnancy. Factors such as the timing of the woman's menstrual cycle can also influence these odds, as the chances of conception are higher during ovulation.

2. Oral Contraceptives and Health Effects: Oral contraceptives, commonly known as birth control pills, are generally safe for most women and are highly effective, with a success rate of about 91% to 99% depending on adherence to the regimen. However, they can have side effects, which may include nausea, weight gain, mood changes, and an increased risk of blood clots, especially in women who smoke or have certain health conditions. It's essential for women considering oral contraceptives to consult with a healthcare provider to discuss their medical history and any potential risks. The benefits often outweigh the risks for many women, especially in terms of regulating menstrual cycles and reducing the risk of certain cancers.

3. Positive Pregnancy Test Response: If a pregnancy test shows a positive result, it is important to confirm the pregnancy with a healthcare provider. There are several options available depending on the individual's circumstances and preferences. If the pregnancy is confirmed, the options typically include continuing the pregnancy, considering adoption, or exploring termination options. Each choice has its implications, and it's crucial to have a supportive environment and access to counseling to make an informed decision. Additionally, early prenatal care is essential if the decision is to continue the pregnancy, as it helps ensure the health of both the mother and the developing fetus.

In summary, understanding contraception is vital for making informed decisions about sexual health. Using condoms significantly reduces the risk of unintended pregnancy, and oral contraceptives are a reliable option for many women, though they come with potential side effects. If faced with a positive pregnancy test, seeking medical advice and exploring all options is crucial. Always consult with a healthcare professional for personalized advice and to address any specific concerns you may have.
