Pregnancy Chances After First Sexual Experience

Probability of Pregnancy

A few months ago, my menstrual periods were on August 23 and September 24.
I had my first sexual intercourse with my boyfriend on October 9 (both of us were inexperienced).
We used a condom throughout the process, and due to pain, he did not fully penetrate.
He did not ejaculate during the encounter.
Afterward, I rinsed to check if the condom had broken; I only rinsed the first third and confirmed it was intact, but the last two-thirds were not rinsed.
My period has not arrived this month, and I took a pregnancy test on October 22 which showed one line.
This morning, October 25, I used morning urine for another test, which also showed one line.
Is there still a possibility of pregnancy? I am very anxious and wondering if my period could be delayed due to excessive stress.
Thank you, doctor.

Hello, the failure rate of contraception using condoms throughout the entire intercourse is over 5%.
Therefore, it is recommended to check for pregnancy if your menstrual period is more than a week late.
There are many factors that can affect the menstrual cycle, such as age, environment, lifestyle, stress, emotional instability, weight changes, medications, emergency contraceptive pills, diet, polycystic ovary syndrome, uterine or cervical lesions, infections, ovulation, pregnancy, and breastfeeding, among others.
Thank you! Wishing you peace and health.

It's completely understandable to feel anxious about your first sexual experience and the potential for pregnancy, especially when you're navigating new territory with your partner. Let's address your concerns step by step, focusing on the medical aspects and providing reassurance.

First, regarding your experience on October 9th, it’s important to note that if you and your boyfriend used a condom correctly throughout the encounter and he did not ejaculate inside you, the chances of pregnancy are significantly reduced. Condoms are a reliable form of contraception when used properly, and they not only help prevent pregnancy but also protect against sexually transmitted infections (STIs).

You mentioned that you checked the condom for any breaks, which is a good practice. However, it's also important to understand that even if the condom was intact, there is still a small risk of pregnancy if pre-ejaculate fluid (pre-cum) comes into contact with the vaginal area. This fluid can contain sperm, although the likelihood of pregnancy from pre-ejaculate is lower than from ejaculate.

Now, regarding your menstrual cycle, it’s common for first-time experiences to cause anxiety, which can indeed affect your menstrual cycle. Stress and anxiety can lead to hormonal changes that may delay your period. If your menstrual cycle is typically regular, a delay can be concerning, but it doesn't automatically indicate pregnancy, especially given the precautions you took.

You mentioned that you took a pregnancy test on October 22nd and again on the morning of October 25th, both of which showed a negative result. A negative pregnancy test is a strong indicator that you are not pregnant, especially if taken after a missed period. Pregnancy tests are most accurate when taken after a missed period, as they measure the hormone hCG, which is produced after implantation. Since your period has not arrived yet, it might be worth waiting a few more days and testing again if it doesn’t come.

If you continue to experience stress about the possibility of pregnancy, consider speaking with a healthcare provider. They can provide further guidance, reassurance, and possibly suggest additional testing if necessary.
In terms of your first sexual experience, it’s essential to communicate openly with your partner about your feelings and any discomfort you may have. If you experienced pain during penetration, it’s crucial to take things slow and ensure that both of you are comfortable. Using lubrication can help ease discomfort, and taking time to engage in foreplay can make the experience more enjoyable.

Lastly, if you have any concerns about your menstrual cycle or reproductive health, don’t hesitate to consult a healthcare professional. They can provide personalized advice and support tailored to your situation.

In summary, based on the information you've provided, the likelihood of pregnancy seems low given the precautions you took, and the negative pregnancy tests further support this. However, if your period does not arrive soon, consider following up with a healthcare provider for peace of mind and further evaluation. Remember, open communication with your partner and seeking professional advice can help alleviate anxiety and ensure a positive experience moving forward.
