Missed menstruation?


Based on the information provided, your girlfriend's last menstrual periods were on February 18 and March 18.
You had genital contact on April 14 without using a condom, but you did not ejaculate.
Since her next expected period was on April 18 and it has not arrived by April 21, there is a possibility of pregnancy, although the risk may be lower due to the lack of ejaculation.
It is advisable for her to take a home pregnancy test for a more definitive answer.
If there are any concerns or if her period does not arrive soon, consulting a healthcare professional would be a good step.

Dr. Zhang Kunmin reply Obstetrics and Gynecology


Hello, the questioner: There is a possibility of pregnancy even if ejaculation has not occurred during intercourse, as pre-ejaculatory fluid may contain sperm.
It is recommended to check for pregnancy if your period is more than a week late.
Thank you! Wishing you peace and health, Dr.
Zhang.

When it comes to the possibility of pregnancy, especially in the context of late periods and sexual activity, it’s essential to understand several factors that can influence the situation. Based on the information provided, your girlfriend's last two menstrual periods were on February 18 and March 18, and you had sexual contact on April 14. Given that her expected period was due on April 18 but has not arrived by April 21, it raises some questions about the likelihood of pregnancy.

Firstly, it’s important to note that the timing of ovulation plays a crucial role in determining the risk of pregnancy. In a typical 28 to 30-day menstrual cycle, ovulation usually occurs around 14 days before the next expected period. If your girlfriend has a regular cycle, she would likely have ovulated around March 31 to April 2. Since you had sexual contact on April 14, which is well after her ovulation window, the chances of pregnancy from that encounter are significantly reduced. However, it is not entirely impossible, especially if her cycle is irregular or if she has a longer cycle.

Another critical factor to consider is the nature of the sexual contact. You mentioned that there was no ejaculation and that the contact was brief. While this reduces the risk of pregnancy, it is important to note that pre-ejaculate fluid (pre-cum) can contain sperm, albeit in lower quantities. If any sperm were present in the pre-ejaculate, there is a slight chance of pregnancy, especially if it came into contact with the vaginal area.

Regarding her late period, several factors can contribute to menstrual irregularities, including stress, changes in weight, hormonal imbalances, or even illness. If your girlfriend has been experiencing stress or changes in her lifestyle, these could potentially delay her period. It’s also worth noting that some women may experience a late period without being pregnant, especially if their cycles are not entirely regular.

Given that her period is late, the most straightforward way to determine if she is pregnant is to take a home pregnancy test. These tests are designed to detect the hormone human chorionic gonadotropin (hCG), which is produced during pregnancy. It is advisable to wait at least a week after the missed period for the most accurate results, but some tests can detect pregnancy a few days before a missed period.

If the test is positive, it would be prudent for her to schedule an appointment with a healthcare provider for further evaluation and to discuss her options. If the test is negative and her period still does not arrive, it may be wise for her to consult a healthcare professional to rule out any underlying issues.

In summary, while the risk of pregnancy from the encounter you described appears to be low, it is not entirely absent. The best course of action is to take a pregnancy test and consult a healthcare provider for personalized advice. Understanding the menstrual cycle, the timing of ovulation, and the nature of sexual contact can help clarify the situation and alleviate concerns.
