Your 15 year old friend who has not yet had her first period may not be protected from pregnancy from the "drop" of semen "on" her vagina. If we assume you mean semen in her vagina, exposure to sperm is certainly a reality. If you mean semen outside of her vagina on the skin of her groin somewhere, that drop outside of her vagina is unlikely to result in pregnancy. I there was intercourse without condom protection or the removal of the condom while the penis remained inside, then again sperm exposure is real. If your friend was depending on penis withdrawal before full ejaculation, that is a calculated risk because there is often an early discharge of sperm before full ejaculation is experienced so the timing of penile withdrawal is only a guess.

Tell your friend about Plan B, a post-exposure birth control medicine that is non-prescription everywhere for persons 17 and older and available with a prescription if under age 17 yrs. Your friend's doctor or Planned Parenthood can provide a prescription for Plan B. This is very effective if taken within 72 hours of the "accident"_ even more effective in the first 1-2 days after semen exposure. If more than 72 hours have elapsed since semen exposure, your friend has purchase at any drug store a urine pregnancy test that she can do 4-6 weeks after the exposure date even though she hasn't had her first menses. Any further concerns can be addressed by her doctor or Planned Parenthood.

Remind your friend that condoms are not just to prevent pregnancy, but also serve to prevent exposure to most Sexually Transmitted Infections (STI's). Encourage her to learn more about all these important issues.

Some day if she continues to have sex without birth control, but unlikely from this episode. She should use birth control in the future.

It is possible to get pregnant,but not necessarily. There for you should always use a condom plus some other birth control method. If she does not get pregnant she will be very lucky and for the future she should start some method of birth control.

She probably wont get pregnant from that drop, but she will likely end up pregnant from the sex she was having before the 'drop' happened. Tell her to use protection next time.

Is it possible , yes. Is it probable no. So this was a lucky pass so count on luck next time. 15 is young and I don't approve of sex for me pts of that age but if u choose to use protection and know how to use it correctly. Stop worrying you will be fine.

Based on the information provided, even though anything is possible, it is unlikely for this to cause pregnancy. It is always important to practice safe sex no matter what.

At this age there could be ovulation.

In that case if the semen GOES inside,she can get pregnant.
