I am on the birth control pill and have been since May 2009 with no issues. I started my last period on January 17th and started my pills that following Thursday, the 21st. I missed one pill the following Thursday, the 28th and then was late taking another the Sunday, the 31st. I left for vacation on Feb 3 and was late taking a few pills, but never went to 24 hours. I had unprotected sex during my vacation and am worried that I may now be pregnant. I took my last pill on Monday the 8th, but still have not started my period. Do you think that it is possible that I am pregnant?
