When it comes to emergency contraception, it is important to understand how it works and the factors that can influence its effectiveness. Emergency contraceptive pills (ECPs), often referred to as "morning-after pills," are designed to prevent pregnancy after unprotected intercourse or contraceptive failure. They are most effective when taken as soon as possible after the incident, ideally within 72 hours, but some types can be taken up to 5 days later.

In your case, you took the emergency contraceptive pill on December 24, and your menstrual period started on December 26. This indicates that the ECP was taken before your expected period, which is a good sign, as it suggests that the pill may have been effective in preventing ovulation. The fact that you had a brief episode of unprotected intercourse on December 30, where withdrawal was used, does introduce a risk of pregnancy, albeit a lower one due to the timing of your menstrual cycle and the use of emergency contraception.

The menstrual cycle is divided into several phases, and ovulation typically occurs around the midpoint of the cycle. If your cycle is regular and you had your period on December 26, it is likely that you were not in your fertile window during the brief unprotected intercourse on December 30. However, sperm can survive in the female reproductive tract for up to five days, so there is still a small possibility of pregnancy if ovulation occurs shortly after the intercourse.

It's also worth noting that emergency contraception does not terminate an existing pregnancy; it works primarily by preventing ovulation or fertilization. If you are concerned about the possibility of pregnancy after taking ECP and having unprotected intercourse, the best course of action is to wait until your next expected period. If your period is late, you should take a home pregnancy test or consult with a healthcare provider for further evaluation.

Regarding your concerns about the potential effects of alcohol consumption during early pregnancy, it is generally advised to avoid alcohol altogether during pregnancy, especially in the first trimester when the fetus is developing. Alcohol can have harmful effects on fetal development, leading to conditions such as fetal alcohol spectrum disorders (FASD). If you suspect you may be pregnant, it is important to stop drinking alcohol and discuss any concerns with your healthcare provider.

In summary, while the risk of pregnancy after taking emergency contraception and having a brief episode of unprotected intercourse is low, it is not zero. Monitoring your menstrual cycle and taking a pregnancy test if your period is late will provide clarity. Additionally, if you have consumed alcohol during this time, it is advisable to consult with a healthcare professional to discuss any potential risks and receive appropriate guidance.
