Could Friction Alone Lead to Pregnancy? Risks and Signs

Will this lead to pregnancy?

On January 29, my girlfriend and I had genital friction, and both of us were very wet, but there was no ejaculation.
We have never had penetration, and she is still a virgin.
However, her period is 9 days late (she has been staying up late recently), and she used a pregnancy test, which showed one line.
I read online that a second line might appear slowly.
Since she only waited 10 minutes before discarding the test, I am still worried about whether she could be pregnant.

More Info

Friction alone, or what is often referred to as "outercourse," can indeed lead to pregnancy, although the likelihood is significantly lower compared to penetrative intercourse. This is primarily due to the fact that pregnancy typically occurs when sperm fertilizes an egg, which usually happens during penetrative intercourse when sperm is deposited in the vagina. However, if there is any transfer of sperm from the male genitalia to the female genitalia during friction, there is a potential risk of pregnancy.

In your case, since you mentioned that there was no ejaculation and that your girlfriend is still a virgin, the chances of pregnancy are relatively low. However, it is important to note that pre-ejaculate fluid (pre-cum), which can be released before ejaculation, may contain sperm. If this fluid comes into contact with the vaginal area, there is a small risk of sperm entering the vagina and leading to pregnancy.

Regarding your girlfriend's delayed menstrual cycle, it is not uncommon for stress, lifestyle changes, or irregular sleep patterns (like staying up late) to affect the menstrual cycle. These factors can lead to a missed or delayed period, which may cause anxiety and concern about potential pregnancy.
You mentioned that your girlfriend used a pregnancy test and received a negative result (one line). Pregnancy tests are generally reliable when used correctly, especially if taken after a missed period. However, it is crucial to follow the instructions carefully, including waiting the recommended time before reading the results. If the test was taken too early or if it was not done according to the instructions, it could lead to inaccurate results.
If your girlfriend is still concerned about the possibility of being pregnant, it would be advisable for her to take another pregnancy test a few days later or consult a healthcare professional for further evaluation. Blood tests can also provide more accurate results and can detect pregnancy earlier than urine tests.

In summary, while friction alone carries a lower risk of pregnancy, it is not entirely without risk, especially if there is any transfer of sperm. The delay in your girlfriend's menstrual cycle could be attributed to various factors unrelated to pregnancy. If there are ongoing concerns, seeking medical advice is the best course of action to ensure peace of mind and proper care.
