My boyfriend and I had sex the day after my period and the condom broke. We went to cvs within the hour and bought plan b one step. About a week after taking it, I had what seemed to be light spotting which was brownish in color and lasted about two days. It's been almost a month since then and I'm super worried because I still haven't gotten my period! Here's a timeline: March 20:took plan b, circa March 26:spotting, March 15 missed period. Now it's March 23, and I still haven't had my period. Last week my nipples were pretty tender, and I've been nauseous this week. Could these just be normal side affects of plan b and my period is just gonna be late, or is it more probable that I'm pregnant?
