ive been on the pill (ortho cyclo lo) for a little over a year. i missed 2 pills and then took 3.. heres why. i went to get more pills on May 10th but the place was closed so i went back on the 11th but they said in order for me to get more i needed my annual exam done but the doctor wasnt there. so thats 2 pills missed in the same week. then i went back on the 12th and got the pills, took all 3 pills of a new pack on the 12th and my fiance and i had sex on the 13th.. my last period was May 6th. and i threw up all yesterday morning.. Could I be pregnant?
