When did you conceive if an ultrasound says are 7 weeks 2 days on April 5?

To calculate the conception date, we need to subtract the gestational age from the date of the ultrasound.

Gestational age = 7 weeks and 2 days = 7 weeks + (2/7) weeks = 7.29 weeks

Converting weeks to days: 7.29 weeks * 7 days/week = 51.03 days

Date of conception = Date of ultrasound - Gestational age in days

Date of conception = April 5 - 51 days

Date of conception = February 21
