I take sertraline and i was wondering if its bad to take the morning after pill while youre taking sertraline?

Don't think so: Plan B and similar morning-after pills can alter the menstrual bleeding for the cycle in which Plan B was taken, and sometimes the next cycle too. One should be sure to check a home pregnancy test about 3 weeks after sex because a morning-after pill works well but not 100% of the time. In general, sertraline doesn't interact with a morning-after pill. The two meds don't interfere with one another.
