Can you become pregnant can you become pregnant by minute amounts of seminal fluid for only a few seconds of penetration?

Yes, : Yes, any contact with seminal fluid can result in pregnancy, even after only a few seconds of penetration. If the patient has any concern for pregnancy, they should take a test if their period is late at all, and if it is negative but the period still doesn't start then wait two days and retake the test. If it is still negative, but the patient doesn't get their period, then she should see a doctor for a blood pregnancy test. The patient should also be seen if there is any concern about sexually transmitted infection.
