That makes your estimated conception date April 12th 2011. However, this date could be wrong by a couple of days. It also depends on when you ovulated.
Your sentence structure is flawed.
Around the 29th of january
The approximate date of conception was May 1st
it would have been around January 10th, 2010.
if i had the baby on the 18th of July when did i conceive?
So her due date was 20th January 2008? Her conception date was roughly Sunday 29th April 2007
January 7, 2012.
Roughly Sunday May 4th 2008, although it depends mainly on your due date rather than on when you baby was actually born
Based on a normal gestation period of 40 weeks the conception date was January 16, 2010.
Unless you are a certain spiecies of animal that carry the baby longer than 9 months, you would have had to conceive in May 07 to have a due date in Jan 08.
Roughly April 11th
April to early may.
