To that date more accurately predict the date of birth of your baby? First ultrasound screening or calendar? My ultrasound due date is just two days before my due date is traditionally calculated.
I must say that the U.S. has been more accurate.
LMP gave me an EDD April 17
9 weeks the United States gave me an EDD April 21
My son was born on April 26
My U.S. TECH said I ovulated almost a week late in the cycle, when we were shocked at such a young baby through the U.S.
According to my last period I had the 7 / 27, but when I had my ultrasound at 20 weeks, because I was predicted around 7 / 20. My doctor has not changed my due date, though.
I have had 18 if ultrasound was more accurate. And I am so happy because waiting was torture!
um and two were bad for me, the calendar date was September 2nd and U / S is the date September 4, but now I'm measuring a week ahead of what they were thinking, technically I have 37 weeks today, but I am now 38 but I'm so close to delivery any day now, they will not change my due date. Mine were wrong because I have PCOS and do not know when I was ovulating and my period was waaay off ... In fact I found out I was pregnant by accident. someone dared me to do a test, surprise!
and if it was your first ultraound perhaps not as accurate because the baby is very small ... so its best to spend the first day of your last period ... Good luck!
My LMP due date is only three days to leave the ultrasound due date.
I was measuring right on pregnancy, so I would say that in my case, they are both accurate, because they are so close together
Ultrasound. The calendar will simply by your last period. Ultrasound can measure their size and the baby. But a difference of two days is not so great. I would say go with whichever is earlier, because believe me when you get there, you do not want to go further. Anything you can think of is to go out and meeting.
