What are the chances of pregnancy after getting your period after the morning after pill?

I had unprotected sex and took the morning after pill the next day, and a week later have my period. I have read that the morning after pill can induce either a late or early period so I hope this is why. But also I know you can be pregnant and still get a period. Do you think I need to take a pregnancy test or I am being overly paranoid?Please answer!! Thanks

well its always better to be safe then sorry.plus you'll be thinking about it all the time untill you put your mind at rest.

no your safe
