Please stick to ONE thread for this issue.

If your final due date is August 22, you most likely conceived on or around November 28 or 29.

Now, you have to remember that this is only an estimate, and is no where near fact. However, since the conception date is estimated about a month after the previous encounter, it is possible that the "best friend" is the father.

Again, this is only an estimate. You will have to have a paternity test once the baby is born for a definitive answer.
