“My period is always really erratic and I took the morning after pill. How can I tell if I missed my period and am pregnant – or if it’s because of the pill?”
After taking emergency contraception it’s normal for your period to be a little later or earlier than usual. EC is pretty good at preventing pregnancy if you take it within five days of unprotected sex, so it’s unlikely you’re pregnant. But you can find out for sure by taking a pregnancy test three weeks after when you took the pill.
