... pre seed. Did this 3 days (Nov. 8), around 8 pm, after I got off of my period and 5 days before my estimated ovulation day (Nov. 14). I had freaked out and took Plan B One Step the next morning (Nov. 9) around 10 am. I'm nervous out of my mind as I read mixed reviews on this pill. I'm scared as I haven't really had any symptoms but I had small head pains and lots of sleeping lately, if those are even symptoms i get from taking it. I just fear it might not work. I just need to ease my mind but I can't with this floating around my brain. So what are the chances of me not getting pregnant?
