Can You Get Pregnant? Risks After Unprotected Intercourse

Can I get pregnant?

The first three menstrual periods occurred on September 29, October 28, and November 27 (with a cycle of approximately 28 to 30 days and lasting about 5 days).
On December 7, I had sexual intercourse with my boyfriend in the early morning.
After oral sex (without ejaculation), he inserted his penis without a condom for about one minute.
I am aware that it takes some time for ejaculation to occur, and I went to the bathroom immediately afterward.
I would like to know what the chances of becoming pregnant are in this situation.

More Info

When it comes to the question of whether you can get pregnant after unprotected intercourse, especially in the context you've provided, there are several factors to consider. Based on your menstrual cycle, which is approximately 28 to 30 days with a duration of about 5 days, we can estimate your ovulation period. Ovulation typically occurs around 14 days before your next period starts. Given your last menstrual period on November 27, ovulation would likely have occurred around December 11 to December 13.
Since you had unprotected intercourse on December 7, this timing is crucial. Sperm can live inside the female reproductive tract for up to five days, so if you were close to your ovulation window, there is a possibility of pregnancy. However, if ovulation occurred after December 7, the likelihood of conception decreases significantly.

Regarding the act of oral sex followed by unprotected vaginal intercourse for a brief period, it is important to note that pre-ejaculate fluid (pre-cum) can contain sperm. Even if ejaculation did not occur during the intercourse, there is still a risk of pregnancy if sperm is present in the pre-ejaculate. The risk is not as high as with full ejaculation, but it is not negligible.

In terms of the probability of pregnancy, studies suggest that the chance of conception from unprotected intercourse can range from 15% to 25% during the fertile window, but this varies based on individual factors such as age, health, and timing in relation to ovulation. Since you are tracking your menstrual cycle, you have a better understanding of your fertile days, which is beneficial for assessing your risk.

If you are concerned about the possibility of pregnancy, it is advisable to take a home pregnancy test if your period is late. These tests are most accurate when taken after a missed period. Additionally, if you are sexually active and not planning to conceive, consider discussing contraceptive options with your healthcare provider to prevent unintended pregnancies in the future.

In summary, while there is a possibility of pregnancy from the scenario you described, the actual risk depends on the timing of ovulation and the presence of sperm. If you have further concerns or experience any unusual symptoms, it would be prudent to consult with a healthcare professional for personalized advice and guidance.
