Early ultrasound is the best we have to accurately calculate your EDD, and if your 7 week and 12 week ultrasounds are giving you the same date then you can be confident in it. Most babies will come within a week plus or minus your due date. Based on your EDD you conceived May 27, plus or minus 2 or 3 days, but it could have occurred from sex several days before.
