Is It Safe? Pregnancy Risks and Emergency Contraception

Is it safe? Is there a risk of pregnancy?

Hello, Doctor.
I have a few questions I would like to ask you.

First: Last month, my girlfriend took emergency contraception to prevent pregnancy due to engaging in water activities.
To calculate her safe period, I would like to know if the first day of her menstrual cycle is still considered the day of heavy bleeding (August 13) after taking the medication.
Her average cycle is about 28 days.
Second: On September 8, I had sexual intercourse with my girlfriend, but afterward, we discovered that the condom was not properly secured and there was some leakage (the semen leaked from the back end, but the condom did not break).
We are concerned about the possibility of pregnancy.
Her period has not arrived yet, and it is now September 15.
Therefore, my girlfriend went to buy emergency contraception.
I would like to know, given her cycle, how likely is it that the sexual intercourse on September 8 could lead to pregnancy? Is it normal for her period to be late? And is the emergency contraception effective?
Third: How many days after the intercourse can we buy over-the-counter pregnancy test kits to check for pregnancy?
Fourth: In the event that she is indeed pregnant, what are some safer abortion methods available within the first month (she is over 20 years old)?
I apologize for the disorganized questions, and I appreciate your guidance.

When it comes to understanding pregnancy risks and the use of emergency contraception, it's essential to address each of your concerns systematically.
First, regarding your girlfriend's menstrual cycle and the use of emergency contraception, if she took a medication to induce menstruation (often referred to as a "menstrual regulation" pill), the first day of her next cycle would typically be counted from the first day of heavy bleeding following that medication. If she experienced significant bleeding on August 13, that would be considered the start of her new cycle. Given her average cycle length of 28 days, her next expected period would be around September 10.
Now, concerning the sexual encounter on September 8, if the condom was not used correctly but did not break, there is still a risk of pregnancy due to potential sperm leakage. The timing of her ovulation is crucial here; if she ovulated shortly after September 8, the chances of conception could be higher. Since her period was due on September 10 and has not arrived by September 15, this could be a sign of pregnancy, but it could also be due to other factors such as stress or hormonal changes, especially after taking emergency contraception.

Emergency contraception (EC) is designed to prevent pregnancy after unprotected intercourse. If your girlfriend took the EC pill within 72 hours of the incident, it is generally effective, but its efficacy decreases the longer one waits to take it. It is important to note that EC can cause temporary changes in the menstrual cycle, including delays or irregular bleeding, which might explain why her period has not yet arrived.

Regarding when to take a home pregnancy test, it is advisable to wait at least one week after the missed period for the most accurate results. This means if her period does not arrive by September 15, she should consider taking a pregnancy test around September 17 or later. Home pregnancy tests are designed to detect the hormone hCG, which is produced after a fertilized egg implants in the uterus.

If it turns out that she is pregnant and you both are considering options, it is crucial to consult with a healthcare provider. In the first trimester, there are generally two main methods for abortion: medication abortion (often referred to as the abortion pill) and in-clinic procedures. Medication abortion typically involves taking two different medications: mifepristone and misoprostol. This method is usually safe and effective up to 10 weeks into the pregnancy. If the pregnancy is beyond this point, surgical options may be considered, and these should be discussed with a qualified healthcare provider.

It is essential to approach this situation with care and sensitivity. Open communication between you and your girlfriend is vital, as is seeking professional medical advice to ensure that both her physical and emotional health are prioritized. Remember, every individual's situation is unique, and healthcare professionals can provide tailored advice based on her specific circumstances.
