| As a new nurse in the Maternity ward, I can tell you that conception dates are totally a guessing game, unless of course the doctor is in the bedroom with you. LOL
What we use is something called Nagele's Rule. It takes the first day of your last period, then subtracts 3 months, adds 7 days, add 1 year, and you have a possible due date. This is still all a guess as there is no way to tell EXACTLY which day you ovulated.
When you ovulate, your egg is only viable for conception for 24 hours, yet sperm can live in a woman's body for up to 3 days. |
