Could i be pregnant? we had sex on oct 11 my last period was sept 26th....everything i read says no because i would have to have conceived oct 10..

Ovulation: Even for someone with regular periods, early or late ovulation happens frequently. This is why the calendar method of birth control isn't much better than no birth control. Your body is designed for reproduction and its quite good at it usually. A home pregnancy test will be accurate a week after the date of the expected period. Best wishes.
