Can i take morining after pill if 2-3 weeks pregnant?

No. You cannot take the morning after pill when you're 2-3 weeks pregnant. The pill is meant to prevent pregnancy and to be taken within a few days after unprotected sex has happened. Taking the morning after pill now will not abort your pregnancy and will likely cause harm to the fetus (especially since the first trimester is a crucial time for development.)

This is also clearly stated on the Morning After Pill box and pharmacists will not give someone who is pregnant this pill.
