Count back nine months from your due date.
Jan 7, 2007
Around March 23rd
Roughly August 15th
Probable date of conception between 11th - 19th November.
nine months from May 7 is February 7. So around then.
The approximate date of conception was June 12 because you follow Naegele's rule so you would add 3 months and subtract 7 days to find the date of conception. If you know the last date of your menstrual cycle you subtract 3 months and add 7 days to find your due date.
You are due sometime around March the seventh.
