More Info

When it comes to understanding the risk of pregnancy after unprotected intercourse, several factors come into play. In your case, since the encounter occurred just two days before your expected menstrual period, the likelihood of conception is relatively low, but not impossible.

Timing of Ovulation
The menstrual cycle typically 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 you had unprotected intercourse just two days before your expected period, it is likely that you were not in your fertile window. Sperm can live inside the female reproductive tract for up to five days, but if ovulation has already occurred, the chances of sperm meeting an egg are significantly reduced.

Use of Emergency Contraception
You mentioned taking emergency contraception (the "morning-after pill") after the encounter. Emergency contraception is most effective when taken as soon as possible after unprotected intercourse, ideally within 72 hours. It works primarily by delaying ovulation, preventing fertilization, or preventing a fertilized egg from implanting in the uterus. If you took the pill promptly, this further decreases the risk of pregnancy.

Other Factors to Consider
1. Menstrual Cycle Regularity: If your menstrual cycles are regular, it can help predict ovulation more accurately. Irregular cycles can make it more challenging to determine your fertile window.

2. Withdrawal Method: You mentioned that your partner only ejaculated on his hand. While this method is not reliable for preventing pregnancy, it does reduce the risk compared to ejaculation inside the vagina. However, pre-ejaculate fluid can contain sperm, so there is still a small risk.

3. Symptoms of Pregnancy: If you experience any symptoms of pregnancy, such as a missed period, nausea, or breast tenderness, it would be wise to take a pregnancy test. Most tests are accurate if taken after a missed period.

4. Consulting a Healthcare Provider: If you have concerns about the risk of pregnancy or the effectiveness of the emergency contraception you took, it is advisable to consult a healthcare provider. They can provide personalized advice and may recommend a follow-up pregnancy test.

Conclusion
In summary, while the risk of pregnancy in your situation is low due to the timing of intercourse and the use of emergency contraception, it is not zero. If you have any doubts or experience any unusual symptoms, taking a pregnancy test or consulting with a healthcare professional would be prudent. Remember, understanding your menstrual cycle and reproductive health can empower you to make informed decisions in the future.
