hi, I have been on birth control pills for about 6 years now. I missed two pills in a row (Tuesday and Wednesday) during the second week of the pack. I took one pill Thursday at my regularly scheduled time. I have had unprotected sex almost everyday including one of the days I missed the pill. I am now bleeding like I have my period along with painful period like cramps and severe nausea, I haven't eaten in two days, except for ginger ale because everything makes me sick even just smells make me nauseous. Could I be pregnant and having symptoms this soon? Or could something else be wrong?
