My girlfriend took the morning after pill the next day after we had sex, we used a condom, the condom did not break, but rather there was a leakage on the botton of the condom after I ejaculated and I was afraid it might have smeared on to her.. Anyway, she took the map on the 12th of january, her last period was on december 31, 2005, and she got her period yesterday the 26 of january, which is more or less on time, but she said she noticed it was lighter than usual.. Should I be worried?.. Any facts/information would be appreciated.. How long does implantation bleeding last? If she gets her period for 5 days normal but lighter does that mean she's okay? What if it's less than 5 days?.. :worried: let me know, thanks
