Can I get pregnant?
I would like to ask the doctor, if I had unprotected intercourse with my boyfriend for about a few minutes and then we stopped, and I took emergency contraception the next day, what is the likelihood of becoming pregnant? Additionally, my last menstrual period started on December 15th; when is the latest date I should wait before seeing a gynecologist if my period hasn't arrived? Thank you, doctor.

Hello, the questioner: There is a possibility of pregnancy even if ejaculation has not occurred during intercourse, as pre-ejaculatory fluid may contain sperm.
The effectiveness of emergency contraception is not 100%, with a failure rate of about 3%, but it is still considered a remedial option.
It is recommended to check for pregnancy if your period is more than a week late.
Thank you! Wishing you peace and health.

More Info
When it comes to the risk of pregnancy after unprotected intercourse, several factors come into play, including the timing of the menstrual cycle, the use of emergency contraception, and individual fertility factors.
In your case, since you had unprotected intercourse and took emergency contraception (commonly known as the "morning-after pill") the following day, you have taken a significant step to reduce the risk of pregnancy. Emergency contraceptive pills are most effective when taken as soon as possible after unprotected intercourse, ideally within 72 hours, but they can be effective up to 5 days after. The effectiveness of these pills decreases the longer you wait, but taking it the next day is a good decision.
Regarding your menstrual cycle, you mentioned that your last period started around December 15. If your cycles are regular and typically last about 28 days, you would expect your next period around January 12. However, since you indicated that your cycles can be irregular, it’s important to consider that ovulation can occur at different times in your cycle. If you had unprotected intercourse close to your ovulation window, the risk of pregnancy would be higher.
If your period does not arrive by the expected date, it is advisable to take a home pregnancy test. These tests are most accurate when taken after a missed period. If the test is positive or if you have any symptoms of pregnancy (such as nausea, breast tenderness, or fatigue), you should schedule an appointment with your healthcare provider for further evaluation.
If your period is delayed by more than a week beyond your expected date, it is also a good idea to consult with a healthcare professional. They can provide you with a blood test for pregnancy, which is more sensitive than home urine tests, and can also help rule out any other potential issues.
In summary, while the risk of pregnancy exists after unprotected intercourse, taking emergency contraception significantly reduces that risk. Monitor your menstrual cycle closely, and if your period does not arrive as expected, take a pregnancy test and consult with your healthcare provider for further guidance. It’s always better to be proactive about your reproductive health, and your healthcare provider can offer personalized advice based on your specific situation.
