Could I Be Pregnant? Risks After Unprotected Intercourse - Obstetrics and Gynecology

When it comes to the possibility of pregnancy after unprotected intercourse, several factors need to be considered. Based on your menstrual cycle and the timing of your sexual activity, we can assess the risk of pregnancy.

You mentioned that your last menstrual period started on January 24, and you had intercourse on February 11 without using a condom and without internal ejaculation. To understand the risk of pregnancy, we need to look at your menstrual cycle and ovulation timing.

Typically, a menstrual cycle lasts about 28 days, but it can vary from person to person. Ovulation usually occurs around 14 days before the start of your next period. If we assume your cycle is around 28 days, ovulation would likely occur around February 7. Since you had intercourse on February 11, this would be just a few days after your ovulation window. Sperm can live inside the female reproductive tract for up to five days, so if you ovulated on February 7, there is a possibility that sperm could still be viable when you had intercourse on February 11.

However, since you mentioned that there was no internal ejaculation, the risk of pregnancy is significantly reduced. While pre-ejaculate fluid (pre-cum) can contain sperm, the likelihood of pregnancy occurring without ejaculation is lower than with ejaculation. Nonetheless, it is not zero, as there is still a chance that sperm could be present in the pre-ejaculate.

Given these factors, the risk of pregnancy from the encounter you described is present but not guaranteed. If you are concerned about the possibility of being pregnant, it is advisable to monitor your menstrual cycle closely. If your period is late by a week or more, you should consider taking a home pregnancy test for confirmation. These tests are generally accurate and can provide peace of mind.

In addition, it is important to understand the significance of using protection during sexual intercourse. Condoms not only help prevent pregnancy but also protect against sexually transmitted infections (STIs). If you are sexually active, discussing contraceptive options with your partner and considering more reliable methods of birth control can help reduce anxiety about unintended pregnancies in the future.

In summary, while there is a possibility of pregnancy given the timing of your intercourse relative to your ovulation, the risk is lower due to the lack of internal ejaculation. Monitoring your menstrual cycle and using a pregnancy test if your period is late will provide clarity. Additionally, consider discussing contraceptive methods with your partner to ensure both of you feel secure and informed about your sexual health.
