What Is More Accurate In Dating Conception, Going 14 Days After The Last Period, Or The Ultrasound Dating?
I know most doctors go by the first day of your last period, then count 14 days and say thats when you should have ovulated,therefor that is when conception was,… so they go by that. But i have had 3 ultrasounds that all match in dates… but a different date than the last period method. Which is more accurate?
