My last cycle in October was all messed up. I got sick and threw up 2 of my pills. I think this messed up my whole cycle because my period came 5 days early so I stopped the rest of my pill pack. My next scheduled active pill was Nov. 8th but i forgot and took my first pill on Nov. 10th. Now I am 4 days late. I had sex on Nov. 5,6,7 unprotected. Looking at the calendar now I realize how "off" I was. From the day I started my period (day 1 of no pills) to the day I took my first pill 13 or 14 days passed. I don't have any symptoms, no sore boobs or anything, but I did have some brown spotting about a week and a half ago along with a day of nausea and headache. Could I be pregnant.
