If your first day of your last period was 23rd May when did you conceive?
The approximate date of conception was June 6th
Around June 3rd to June 13th. Your due date is 40 weeks after the first day of your last period. You actually conceive while you are fertile which is usually about 2 weeks AFTER the first day of your last period. So technically, the day you become pregnant, you are usually (medically speaking) 2 weeks pregnant.
