Since my edd is 01/22/13 I'm pregnant by the guy a - sex april 28, 29 & may 1st. Guy b was april 6 or 7, can't recall but it wasnt sex actually.?

Guy "A" If your dates have been confirmed by a first trimester ultrasound, the baby daddy is guy "a". Sexual activity that results in a pregnancy must have vaginal penetration with the deposit of sperm. What is your meaning of "sex"?
