I took Plan B within 30 minutes of having sex. The condom had broke so it was just a precaution. A week after I’ve been bleeding a little here and there. At first it was a brown discharge but for the pass two days it has been blood. Kind of spotting. Could this mean I’m pregnant? I know I’m not supposed to start my period because I started on 1/1/18 and finished 1/5/18 and had sex and took Plan B on 1/9/18. I do not know if this is a side effect of the Plan B?
