Pregnancy Chances and Early Symptoms After Unprotected Intercourse

Probability of Pregnancy

My last menstrual period started on January 5th, and my cycle varies between 33 to 35 days.
I had unprotected sexual intercourse on January 23, 24, and 25, using condoms throughout.
Afterward, I checked for any breakage with water and found none, but during the process, the condom slipped slightly forward, though it didn't seem to leak.
My period is now 10 days late.
I would like to ask: 1.
What is the likelihood of pregnancy in this situation? 2.
If I am pregnant, how many weeks along would I be? 3.
Recently, I've been experiencing some abdominal pain, a feeling of fullness in my stomach, increased appetite, diarrhea, and gas.
Are these early pregnancy symptoms or premenstrual symptoms?

Hello, based on your description, there is a possibility of pregnancy, as the failure rate of correctly using condoms is still around 5%.
Generally, it is not recommended to rely solely on condoms for contraception.
It is not possible to determine pregnancy based on subjective symptoms.
I suggest that if your period is one week late, you should take a urine test to check for pregnancy.
If necessary, please consult a physician for evaluation.
Thank you! Wishing you safety and health.

More Info

When it comes to understanding the chances of pregnancy and early symptoms after unprotected intercourse, it's essential to consider several factors, including the timing of your menstrual cycle, the nature of the sexual activity, and the symptoms you are experiencing.

1. Pregnancy Probability: Based on the information provided, your last menstrual period started on January 5, and you typically have a cycle length of 33 to 35 days. This means that your next expected period would be around February 7 to February 9. Engaging in sexual intercourse on January 23, 24, and 25 while using condoms significantly reduces the likelihood of pregnancy, especially if the condoms were intact and there was no leakage. However, since you mentioned that the condom slipped slightly, it is important to consider that there is still a minimal risk of pregnancy if any semen came into contact with the vaginal area. Given that your period is now 10 days late, it is advisable to take a home pregnancy test to confirm whether you are pregnant or not.

2. Determining Weeks of Pregnancy: If you are indeed pregnant, the gestational age is typically calculated from the first day of your last menstrual period. Since your last period started on January 5, and assuming you conceived around the time of your sexual activity, you would be approximately 4 weeks pregnant. However, this is a rough estimate, and the exact timing can vary based on ovulation and conception.

3. Symptoms: The symptoms you are experiencing—abdominal discomfort, increased appetite, diarrhea, and gas—can be indicative of early pregnancy, but they can also be related to premenstrual syndrome (PMS) or other gastrointestinal issues. Early pregnancy symptoms often include nausea, breast tenderness, fatigue, and changes in appetite, but they can overlap with PMS symptoms. The abdominal pain and discomfort could be due to hormonal changes or even anxiety about the possibility of being pregnant.

In summary, while the chances of pregnancy seem low given the precautions taken, the delay in your period warrants a pregnancy test for confirmation. If you test positive, you can consult with a healthcare provider for further evaluation and to discuss your symptoms. If the test is negative and your period does not arrive soon, it may be wise to consult a healthcare professional to rule out any underlying issues. Remember that stress and anxiety can also affect your menstrual cycle, so it's important to take care of your mental health during this time.
