Had sex on 21 dec then again 29dec-7jan. due date 28th sep. when did i conceieve?

Conception dates: Assuming you usually have a cycle that's around 28 days from the start of one period to the start of the next and assuming ultrasound confirmed your due date, then conception would have occured around january 2nd. This is an approximation, so if there is more than one potential father, always always consider paternity testing.
