Danielle, Female, 25 One Week Before My Period Was Due

Danielle, Female, 25

One week before my period was due I had unprotected sex at 7:00am, I went and got the morning after pill (levonelle) and took it at 10:30am the same morning.

It's been 6 weeks since I took the morning after pill, and my period has not arrived (no light bleeding, no brown discharge). I have taken a pregnancy test, which showed up negative.

Would the reason for no period most likely be my hormones from the morning after pill, or pregnant.

I have taken the morning after pill on 2 other occasions, both times my period came when due.
