Only possible conception dates: 7/4 and 7/18-23rd my first ultrasound dated me at 13 weeks 5 days.with a conception date of 7/20.how accurate is this?

Good Enough: Sounds like your sono dated you in the middle of the 7/18-23 range. No way was it the 7/4 window. Accuracy should be less than a week either way.
