how to determine the conceive date
Do the math! However, this is how to determine an estimated date of conception if you havenât been tracking your cycles. First of all, determine the date that you started your last period, and mark it down, if you havenât already. Then add eleven days to the date your last period started. This is the first day that it was possible for you to conceive. Now, add another ten days to the first day that conception was possible. Those ten days are the days that it is possible for you to have conceived. You will have to narrow it down within those ten days to determine what your actual date of conception was.
