I started birth control on Sunday June 4 2011 and had intercourse on June 11 and 12 I used condoms as back up but not sure if it broke... On June 22 I had cramps and stopped taking the birth control and started bleeding somehat lighty for 3days... On July 24th I took a pregnancy test and it is positive.. All month of July I stopped the birth control and condom use... I'm trying to figure when was it possible I became pregnant

My periods are always irregular so I'm not sure when my last period was before I began the pack on June 4th 2011. I believe that why I started getting cramps around the 22nd of June
