My educated guess would be that your last period began around June 30 so ovulation probably ocurred about 14 days later which would be July 14th. I think the greatest chance of conception ocurrs around ovulation time like 3-5 days prior to or up to 2 weeks after ovulation.
Sometime around late August 2007 or early September 2007 is when you became pregnant
The approximate date of conception was April 26th
September
Around Dec 27th 2007
The approximate date of conception was May 3rd
answer would be June 2nd 2007 Yvonne
sometime in September
Around mid-April or mid-May
If your due date is May 14, 2010 you are 9 weeks pregnant
July
The approximate date of conception was May 1st 2009.
Count back nine months: October September August, July June may, April march, February You became pregnant around February 27, 2007.
