missing 10 pills

I have been on birth control for three consecutive years my youngest child is 3. I started my last period on April 14 and it ended on April 18. I also started my pack of ortho-tri-cyclen and I took the first three pills out of the pack. I then missed the next 14 pills. I had unprotected sex on the 11th day and had bleeding ffrom the 8th through the 10th days. I was on antibiotics for a sinus infection during the week of April 16th. What do you think my chances of being pregnant are? Please answer me anyone A.S.A.P!!!!!!!!

Were you prenant?? I am in a similar situation now. Had a period on July 4th, took 3 active pills, and then went off them altogether. Had another 5 days period on July 15th & have had sex every day since. I want to know if I could be pregnant!!
