In May, there were 1-2 instances of sexual intercourse, and safety measures were properly taken without any breakage.
The menstrual period in April started on April 4th, and in May it started on May 2nd.
However, it is now the 6th of June, and menstruation has not yet occurred.
Is it possible that I am pregnant? Answer: Since proper safety measures were taken and there was no breakage, it is unlikely that pregnancy has occurred.

When it comes to the possibility of pregnancy after engaging in sexual activity, especially when precautions have been taken, it's important to understand the factors at play. Based on your description, you had sexual intercourse in May with proper protection, and your last menstrual period started on April 4th and ended on April 9th, while your May period began on May 2nd and ended on May 6th. Now, you are concerned because your period has not arrived by June 6th.

First, let's clarify the menstrual cycle. A typical menstrual cycle lasts about 28 days, but it can vary significantly from person to person, ranging from 21 to 35 days. Ovulation usually occurs about 14 days before the start of your next period. If your cycle is regular and you have a typical 28-day cycle, your next period would be expected around May 30th. However, if your cycle is longer or irregular, the timing of ovulation and menstruation can vary.

Regarding the sexual activity you mentioned, if you used condoms correctly throughout the entire process and there were no breakages, the likelihood of pregnancy is significantly reduced. Condoms are about 98% effective when used perfectly, but in real-world scenarios, the effectiveness drops to about 85% due to human error. It's also important to note that pre-ejaculate fluid can contain sperm, which is a risk factor if the condom is not applied before any genital contact.

Now, concerning your late period, there are several reasons why you might not have gotten your period yet:
1. Stress: High levels of stress can affect your hormonal balance and delay your menstrual cycle. If you've been experiencing anxiety about potential pregnancy, this could contribute to a delayed period.

2. Hormonal Changes: Various factors, including weight changes, exercise levels, and hormonal imbalances, can affect your menstrual cycle.
3. Pregnancy: While you mentioned using protection, no method is 100% effective. If there was any chance of sperm entering the vagina, it is still worth considering a pregnancy test if your period does not arrive soon.

4. Other Health Issues: Conditions such as polycystic ovary syndrome (PCOS), thyroid disorders, or other health issues can also lead to irregular periods.

Given that it is now June 6th and your period is late, I recommend taking a home pregnancy test for a definitive answer. These tests are generally reliable and can provide results as early as the first day of your missed period. If the test is negative and your period still does not arrive, or if you have any unusual symptoms (such as severe pain, unusual discharge, or other concerning signs), it would be wise to consult a healthcare provider for further evaluation.

In summary, while the use of condoms significantly reduces the risk of pregnancy, it is not infallible. If your period is late, consider taking a pregnancy test and consult with a healthcare professional if you have further concerns. Remember, maintaining open communication with your partner about sexual health and contraception is crucial for both of your peace of mind.
