I think its the pill that made you lose your period... But if you missed your period you don't lose anything to take a pregnancy test you might be pregnant good luck :)
i'm having the same problem. missed mine last month and it normally comes around this time each month and im still waiting. im on birth control, use condoms %26amp; pulls out. its like impossible for me to be prego. gyno appt next week, ill see whats up. i know bc can cause you to not have a period, but mine have always been regular so this is odd.
