some help

Jaime

So my due date is may 3rd. first day of my last period was july 27th. Well looking back i had 2 periods in july. the first one starting on july 2nd and the other July 27th. my baby is measuring a little bigger than 15 weeks. could it be possible that I conceived after the July 2nd period? I go Tuesday to my ob so going to ask her. just wanted to see what everybody else thought.
