On the 1st of September, I had unprotected sex with my boyfriend and less than an hour later, I took an Escapelle pill (morning after pill). My period was supposed to come the day after on the 2nd of September but it didn't. Instead, from the 1st to today, the 7th of September, I have had pains similar to those I have whenever I am about to have my periods but there wasn't and still isn't any sign of me menstruating. I have missed my period. Is it possible that I might be
pregnant?
