If you were 5 weeks and 6 days on sept 9th 2009 when did conceive?

To calculate the date of conception, we need to subtract the number of weeks and days from the given date.

Given date: September 9th, 2009

Gestational age: 5 weeks and 6 days

Calculation:

1 week = 7 days

5 weeks = 5 x 7 = 35 days

35 days + 6 days = 41 days

Counting backward 41 days from September 9th, 2009:

September 9th - 41 days = August 31st, 2009

Therefore, the estimated date of conception is August 31st, 2009.
