I had protected sex on September 1, one day after my period ended. when my boyfriend pulled out he noticed the condom broke. within 2 hours I took plan b onestep. a week later I started spotting and have had a brownish discharge and cramps...the brown discharge lasted about 2 weeks. my cycle is very consistent and my period should have started on the 21st. I was cramping pretty badly the 19-21 and on the 21st it seemed like it was more my period than the brown discharge...but only for a day or 2. now for the past few days I've still been cramping every so often, but now I have a pinkish discharge. could I be pregant????
