You would be due for a complete ultrasound for anatomy in a week or two. Also you will need prenatal labs if they are not yet done. Good prenatal care is key to a healthy outcome.

Edd 8th february 2014 and baby was born 4th february 2014. Do I count back 9 months from the 4th to get conception date as LMP was 6th may?

5 /20: If may 6th 2013 was your LMP date, then average date of conception would be around may 20th. Based on your due date, your conception date would be may 18th, so very close. Somewhere between 5/ 18 and 5/20 you likely conceived. ...Read more

Due date/time of conception, when? My LMP oct17/13 edd 7/24/14. Dec4/13 vag u/s 7w3d+/-5d edd 7/20/14 but u/s on 2/28/14 read 20w4d edd 7/15/14?

See below...: 1. Lmp = 10/17
2. U/s = 7 3/7 wks on 12/4

based on these initial two criteria for dating the pregnancy, your due date would typically be based on your LMP dating because they only disagree by 4 days. In our practice, we would list your due date as 7/20. At your 20 weeks scan, agreement with a 7/20 due date within 5 days is normal and reflects normal growth. ...Read more

LMP 10/25/14. EDD 8/1/15.Had u/s done at 12 weeks that dated 3 days before LMP, which is 10/22/14. What do that mean? Do u/s measure from conception?

Good dates: Best dating criteria for determining gestational age is your LMP. Weeks are by convenient counted starting from the first day of the LMP, and the expected date of delivery is 40 weeks after the first day of the LMP. This same convenient is used when gestational age is estimated by ultrasound, but ultrasound (US) can not estimate gestational age exactly and dates within 3 days is very close. ...Read more
