Hello Dr. Chang, regarding the safe period, could you please assist me? Thank you?

Hello Dr.
Chang,
Xiao Ting has provided you with the first day of her menstrual cycle for the past year.
She is planning to travel with her boyfriend on February 19, 2013, and they may engage in sexual intercourse, which seems to coincide with her estimated ovulation day.
Although she has calculated this herself, she would like your assistance.
Below are the first days of her menstrual cycles:
Year 101:
2/19, 3/16, 4/11, 5/8, 6/6, 7/5, 8/1, 8/30, 9/28, 10/23, 11/18, 12/14
Year 102:
1/10, 2/7
Dr.
Chang, if sexual intercourse occurs on February 19, what contraceptive measures should I take? My boyfriend always uses condoms throughout the entire act.
Typically, after I perform oral sex, he puts on the condom, and his glans does not come into contact with me.
Additionally, during showering, there is no contact either.
Aside from this, we do not use any other contraceptive methods.
If we engage in sexual intercourse during the fertile window while using a condom (which is used throughout), what is the likelihood of pregnancy? Can my boyfriend and I enjoy our intimacy on February 19?
Secondly, if my boyfriend removes the condom after ejaculation on my chest and we shower, can we engage in sexual intercourse again immediately afterward, still using a condom? Will the sperm be killed by the hot water in the shower, as I have heard that sperm are sensitive to heat?
Lastly, I would like to inquire about the current regulations regarding abortion.
Is it true that one must be at least 20 years old to undergo the procedure without the consent of a legal guardian, or can consent from family members suffice? Can the boyfriend's family also provide consent?
Thank you, Dr.
Chang, for taking the time to respond to Xiao Ting's inquiries amidst your busy schedule.

Hello, the inquirer: Your menstrual cycle has been irregular in the past, with varying days of early onset, making it difficult to calculate the safe period.
Even with a regular cycle, it is not advisable to rely on this method for contraception.
The failure rate of using condoms consistently is about 5% (approximately 1 in 20 times will result in pregnancy), and sperm can be present in pre-ejaculatory fluid.
I recommend using oral contraceptives to prevent failure.
RU486 can only be consented to by individuals over 18 years old, but it also has a failure rate and potential side effects.
It is advisable to engage in sexual activity cautiously and practice careful contraception.
Thank you! Wishing you peace and health, Dr.
Zhang.

When it comes to understanding safe periods and contraceptive measures for young couples, it’s essential to consider several factors, including the menstrual cycle, the timing of ovulation, and the effectiveness of contraceptive methods like condoms.

Understanding the Menstrual Cycle and Ovulation
The menstrual cycle typically lasts about 28 days, but it can vary from person to person. Ovulation usually occurs around 14 days before the start of the next menstrual period. For example, if your cycle is regular and your last period started on February 7, ovulation would likely occur around February 21. This is considered the "fertile window," where the chances of conception are highest if you engage in unprotected sexual intercourse.

Contraceptive Measures
1. Condom Use: Using condoms is one of the most effective ways to prevent both pregnancy and sexually transmitted infections (STIs). If your boyfriend consistently uses condoms throughout the entire sexual encounter, including during oral sex and vaginal intercourse, the risk of pregnancy is significantly reduced. However, no contraceptive method is 100% effective, so it’s wise to consider additional methods if you are concerned about pregnancy.

2. Emergency Contraception: If you have unprotected sex during your fertile window, emergency contraception (like Plan B) can be taken within 72 hours to reduce the risk of pregnancy. It’s important to consult with a healthcare provider for guidance on this option.

3. Timing of Intercourse: If you plan to have sex on February 19, and it coincides with your ovulation period, the risk of pregnancy is higher. However, if you use condoms correctly throughout the encounter, this risk is mitigated.

Post-Intercourse Considerations
If your boyfriend removes the condom after ejaculation and you wash up, it’s important to ensure that any residual sperm is not transferred back into the vagina. While washing can reduce the number of viable sperm, it’s not a foolproof method. If you plan to have sex again shortly after, using a new condom is crucial to prevent any risk of pregnancy.

Concerns About Temperature and Sperm Viability
Regarding your question about whether sperm can be killed by hot water, while it’s true that sperm are sensitive to temperature, the likelihood of washing away all viable sperm is not guaranteed. Sperm can survive for a short period outside the body, and if any sperm remain on the skin, there is a potential risk of pregnancy if they come into contact with the vagina.

Legal Considerations for Abortion
In many jurisdictions, the age of consent and the legal requirements for obtaining an abortion can vary. Generally, individuals under the age of 18 may need parental consent or notification, depending on local laws. It’s advisable to consult with a healthcare provider or a legal expert in your area to understand the specific requirements.

Conclusion
In summary, if you and your boyfriend are planning to engage in sexual activity during your fertile window, using condoms consistently and correctly is essential for preventing pregnancy and STIs. If you have any concerns about potential pregnancy or the effectiveness of your contraceptive methods, consider consulting with a healthcare provider for personalized advice. Additionally, understanding the legal implications surrounding reproductive health in your area is crucial for making informed decisions. Always prioritize open communication with your partner about sexual health and contraception to ensure both of you feel comfortable and secure.
