Could My Girlfriend Be Pregnant If Her Period Is Late?

May I ask the doctor?

My girlfriend's menstrual cycle is usually irregular; sometimes it comes at the end of the month and other times at the beginning.
In November, I engaged in intimate activities with her, but there was no penetration.
I did, however, rub my genitalia against her buttocks and relieved my sexual urges through masturbation.
It seems that I may have come into contact with her underwear.
A week or two later, my girlfriend got her period, and as of today, we have not engaged in any sexual activities.
However, my girlfriend mentioned that her expected period has not arrived.
Is there a possibility of pregnancy?

It is possible that irregular menstrual cycles are causing the delay.
If you are concerned about pregnancy, you can purchase a home pregnancy test to check for pregnancy.

When it comes to the possibility of pregnancy, it’s essential to understand how conception occurs and the factors that can influence menstrual cycles. In your case, you mentioned that you engaged in intimate activities with your girlfriend in November, but did not have penetrative intercourse. Instead, you described a situation where your genitalia may have come into contact with her underwear. This raises the question of whether there is a risk of pregnancy from such activities.

Firstly, it is important to clarify that pregnancy typically occurs when sperm fertilizes an egg. For this to happen, sperm must be deposited in or near the vaginal canal, allowing it to travel to the egg. In your situation, since there was no direct penetration and only potential contact with her underwear, the likelihood of sperm reaching her vagina and resulting in pregnancy is extremely low. Sperm cannot survive long outside the body, and the chances of it being transferred from your genitalia to her vagina through clothing are minimal.

However, you also mentioned that your girlfriend's menstrual cycle is irregular. Irregular cycles can be caused by various factors, including stress, changes in weight, hormonal imbalances, and lifestyle changes. If her period is late, it could be due to these factors rather than pregnancy. Stress, for instance, can significantly impact the menstrual cycle, causing delays or missed periods.
Given that your girlfriend had her period in November and has not engaged in sexual activities since then, it is possible that her late period is a result of her irregular cycle rather than pregnancy. If she typically has a regular cycle, a delay of a few days may not be unusual, but if she is significantly late, it might be worth considering a pregnancy test for peace of mind.

In summary, while the possibility of pregnancy in your described scenario is very low, it is not entirely impossible. If your girlfriend is concerned about her late period, the best course of action would be to take a home pregnancy test. These tests are generally reliable and can provide clarity on whether or not she is pregnant. If the test is positive or if her period remains absent, it would be advisable for her to consult a healthcare professional for further evaluation and guidance.

In conclusion, while the risk of pregnancy in your situation appears to be minimal, it is always best to err on the side of caution. Open communication with your girlfriend about her concerns and encouraging her to take a pregnancy test can help alleviate anxiety and provide clarity on the situation.
