A member asked:

My edd by the transvaginal ultrasound at 6 weeks 3 days was 2/1/13. what possible days could i have conceived?

2 doctors weighed in across 2 answers

Around 5/10: Depending on your cycle, may 10 would be the approximate date of conception if you were having regular 28 day cycles.

Subtract: 4weeks from 6weeks three days, the date of your scan, and that will be within 3-4 days.
