Then you probably conceived on approx April 22nd. If you had conceived on May 6th your due date would be around 2/10/11
My LMP was 4/09/10. My original due date was 1/1/11 then was changed to the 16th.
My original due date by my calculations was 1/11/11 but was changed to 1/6/11. I conceived April 12th. You most likely conceived in April as well.
I am due 12/30/10, my exact conception date is 4/8/10 if this helps any... My due date has never changed and at the date of conception your egg starts at 2 weeks. Sorry to say so, but you possibly could be looking into May for a conception date
