So going from what they are saying it is 6 days diff, going by me i make that 7! But when i went for my 2nd scan i made it that i was 20 2, but from last period they say 19 2, scan showed 20. Basically they say it is more accurate to go by your first scan & in my case i make it that i was 7 days diff so they should have changed my due date, but they say 6 days so i keep the later due date.
Ultrasound scans use sound waves to build a picture of the baby in the womb.
The date of your last period is only a rough estimate, dating scans they go by measuring the size of the baby.
It may be a few days off, as in when you have your 20 week scan you might go forward/back again, but its pretty accurate!
Sydney ultrasound for women said when they did my ultrasound that a dating scan for them can be plus or minus up to 5 days. So maybe you ovulated a little later than you thought?
So there is a 2 week difference from my EDD and theirs.
Its located on left hand side of menu when ur on your home page.
Because as u say if they only put you at 10 weeks pregnant and u found out 9 weeks ago I wouldnt imagine u could start having morning sickness as early as early as u did. x A girl at my work went for her first scan last week and they told her she was 4 weeks further on than she had expected..
x the same happened to me i fort id be due first week in march according to my period dates and tht but scan sed im not due til march 20th.., really confusen they can change it at u nxt scan my cousin had her date's changed at her 20 week scan ow u n bump?
xx Well i went for my 1st scan i was 11 2, they put down from my last period 11 3 they then put me ahead saying i was 12 2.
