Being your only on the 2nd month of taking the pill your body is still adjusting. Lighter periods (just brownish discharge) should be normal. Sometimes hardly anything at all. Missing pills can mess it up even more. You are probably not PG. But perhaps a scare to be sure and not miss your pills! Get a good routine, Brush your teeth, take your pill. And pulling out doesn't stop pregnancy.Just take another test in a few days to be sure. Sorry if I sound mom like but my daughter is 20 and been on several different pills.
