The last day of my period was nov 20. I had sex both nov 26th and 27th took plan b that same day but i havent gotten my period since. I haven't taken a pregnancy test but I've had nausea, vomiting, fatigue, and bloating most of all. On feb 4th I began having light spotting and the 5th and 6th and today I've been having really bad cramps and heavy bleeding it looks like my period would normally look like. Could I have been pregnant and miscarried? Am a bit confused ?
