Hi, I'm 22, and I am 10 days late on my period. I have had unprotected sex most of last month and the month before I took a plan b (if that means anything). I have been spotting for three or four days now, only when I use the bathroom though and this last day I had a little heavier spottng but it seemed watery. I am more moody than usual, light cramps, and my appitite has increasingly changed. I am however under alot of stress. Any conclusions? I'm not sure what to do with this....
