me and my boyfriend had unprotected sex on October the 2nd which was a Friday and I was cramping then like I was going to come on but didn't... and was on my placebo pills . I started a new Pack on Tuesday and still haven't started my period. I am cramping a little and been having stomach issues all week. Am I pregnant? I take my pill at almost the same time everyday ... and if not I'm normally only like an hour or two late.
