Teenager taking birth control pill.
A contraceptive pill that would work up to a month after unprotected sex is a realistic possibility, according to a new paper in a leading medical journal.
The authors of a paper in the Journal of Family Planning and Reproductive Health Care say that the drug would function similarly to the morning-after pill (taken within 72 hours of sex) but could be used only after a missed period, or on a regular basis — perhaps as little as once a month.
“A woman could potentially use a post-fertilization method on a planned schedule only once in each menstrual cycle, no matter how many prior coital acts she had had in that cycle,” wrote the scientists from the U.S. and Sweden.
