Emerg. contraception: The emergency contraceptive morning-after pill taken soon after sex is very effective in preventing pregnancy. It is about 95% effective, which translates to: if 100 women take the pill the day after sex, about 95 will not get pregnant from that sex. One can do a urine pregnancy test about 3 weeks after sex, to make sure there is no pregnancy.
