I took the morning-after pill on a Tuesday, and after 3 I had to take another one. Are there chances of pregnancy?
Expert answer:

The next day pill was created for special situations and its use should be eventual, have a high dose of hormones and can lead you to have health problems. And yes, there are chances of pregnancy because the effect of the morning after pill is not 100% effective. You need to use another contraceptive method.
