Re: Me And My Girlfriend Had Sex Without A Condom!!!!
Continuing to have sex after ejaculation, just wiping off the ejaculate is very risky I should think. Even urinating between doesn't always prevent pregnancy. That's why the withdrawal method is not a form of birth control at all.
My advice to you--if it's under 72 hours since it happened (and the sooner the better), see about getting her Plan B from the pharmacy or Planned Parenthood.
She is at greatest risk for pregnancy from 9-18 days from the first day of her last period (a woman is most fertile around ovulation, but this can occur at varying days for different women; day 14 is the standard for textbook cycles, but sperm can live up to 5 days if conditions are right in the woman's vagina, and some women ovulate later than day 14).
For a pregnancy test to be most accurate, she needs to wait until her period is expected (preferably wait until her period is at least 1 day late) and then test. However, stressing about being pregnant can make her cycle wacky too.
