Am I Pregnant? Risks and Delays in Menstrual Cycle - Obstetrics and Gynecology

Is it pregnancy?


I had sexual intercourse with my boyfriend for the first time on July 24th.
We used a condom, but during the second time, we didn't use one; I only inserted a few times without ejaculation.
We had intercourse again on July 31st, but the condom broke, and there was no ejaculation.
Out of fear, I bought emergency contraception and took it.
My period was supposed to arrive on August 3rd, but it hasn't come yet.
I also noticed that my vaginal discharge isn't very much, and my body temperature is around 37.2-37.4°C.
Could I be pregnant? Could the encounter on July 24th lead to pregnancy? Since I took the emergency contraception on July 31st, is there still a chance of pregnancy? Can taking the medication cause a delay in my period? Is it normal for my period to be four days late?

Hello, Miss Anonymous: Taking emergency contraceptive pills often leads to menstrual irregularities.
Since your period has lasted for four days, you should take a urine test to find out.
It's hard to say whether you could be pregnant from the sexual activity on July 24th, but the chances are likely low.
Taking emergency contraception does not guarantee 100% effectiveness in preventing pregnancy.

More Info


Determining whether you are pregnant can be a complex process, especially when considering various factors such as timing of sexual intercourse, contraceptive methods used, and any medications taken. Based on the information you provided, let's break down the situation.

You mentioned having unprotected intercourse on July 24 and July 31, with the first instance using a condom and the second instance being without one, although there was no ejaculation. The timing of your menstrual cycle is also important; your period was expected on August 3, but it has not arrived yet, which is now four days late.

1. Potential for Pregnancy: The risk of pregnancy from the encounters you described depends on several factors. Sperm can survive in the female reproductive tract for up to five days, so if you ovulated shortly after your sexual encounters, there is a possibility of conception. The first encounter on July 24 could potentially lead to pregnancy if ovulation occurred within that timeframe. The second encounter on July 31, although it involved no ejaculation, still carries some risk due to pre-ejaculate fluid, which may contain sperm.

2. Emergency Contraception: You mentioned taking medication after the incident on July 31. If this was an emergency contraceptive pill (ECP), it can significantly reduce the chance of pregnancy if taken within 72 hours after unprotected intercourse. However, ECPs can also cause changes in your menstrual cycle, including delays in the onset of your period. This could explain why your period is late.

3. Menstrual Cycle Variability: It is not uncommon for menstrual cycles to vary in length due to various factors such as stress, hormonal changes, or the use of medications. A delay of a few days can be normal, especially if you have recently taken emergency contraception, which can disrupt your hormonal balance temporarily.

4. Symptoms and Testing: You mentioned experiencing a slight increase in body temperature and changes in vaginal discharge. While these can be early signs of pregnancy, they are not definitive. The most reliable way to determine if you are pregnant is to take a home pregnancy test. These tests are designed to detect the hormone hCG, which is produced after a fertilized egg implants in the uterus. It is best to wait until at least the first day of your missed period for the most accurate results.

5. Next Steps: If your period does not arrive soon, I recommend taking a home pregnancy test. If the test is positive, you should schedule an appointment with a healthcare provider to confirm the pregnancy and discuss your options. If the test is negative and your period still does not come, consider consulting a healthcare professional to explore other potential causes for the delay.

In conclusion, while there is a possibility of pregnancy based on your sexual encounters, the use of emergency contraception and the natural variability of menstrual cycles can also explain the delay. Taking a pregnancy test will provide clarity, and if you have further concerns, seeking medical advice is always a good step.
