Hello, the questioner: There is a possibility of pregnancy even if ejaculation has not occurred during intercourse, as pre-ejaculatory fluid may contain sperm.
Additionally, the effectiveness of emergency contraception is not 100%, with a failure rate of about 3%.
Early pregnancy may not present specific symptoms, and subjective symptoms cannot be used to make a determination.
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

Unprotected sex during ovulation significantly increases the chances of pregnancy. Ovulation is the time in a woman's menstrual cycle when an ovary releases an egg, making it available for fertilization. This typically occurs around the midpoint of the cycle, and sperm can survive in the female reproductive tract for up to five days. Therefore, if unprotected intercourse occurs on or just before ovulation, the likelihood of sperm meeting the egg is quite high.

In your case, since the unprotected intercourse occurred on December 18, which was the last day of your girlfriend's ovulation period, there is a possibility that she could become pregnant. The emergency contraceptive pill (often referred to as the "morning-after pill") is designed to prevent pregnancy after unprotected sex, but its effectiveness decreases the longer you wait to take it after the incident. If taken within 72 hours, it can reduce the risk of pregnancy by up to 89%, but it is most effective when taken as soon as possible.

The symptoms you are experiencing, such as a feeling of nausea, can be side effects of the emergency contraceptive pill. Common side effects include nausea, fatigue, headache, and changes in the menstrual cycle. These symptoms do not necessarily indicate pregnancy, especially if they are occurring shortly after taking the emergency contraceptive. However, if your girlfriend's period is delayed by more than a week, it would be advisable for her to take a pregnancy test to confirm whether or not she is pregnant.

If you are concerned about the possibility of pregnancy, it is important to monitor her menstrual cycle closely. If she experiences any unusual symptoms or if her period is significantly late, a pregnancy test can provide clarity. Additionally, if there are any concerns about the effectiveness of the emergency contraceptive or if she experiences severe side effects, consulting a healthcare provider is recommended.

In conclusion, while the chances of pregnancy after unprotected sex during ovulation are high, the use of emergency contraception can significantly reduce that risk. The symptoms you are experiencing may be related to the emergency contraceptive rather than an indication of pregnancy. It is essential to follow up with a pregnancy test if her period is late and to consult a healthcare professional for any further concerns.
