Sounds like the first guy. Do you know that doctors count the time allotted to pregnancy (the "weeks pregnant") as beginning on the first day of your last period, or on a computed first day of your last period if working from an ultrasound? It sounds like you were already pregnant by the time you had sex on July 16.
