I don't know about the measurement of the sac but at 8 weeks you should more than likely see a yolk sac and fetal pole and possibly the heartbeat as well.  Were any of those present?

maybe she is not as far along as she thought, not everybody ovulates on day `14, did they see anything else on the sac.

at 6 weeks the gestational sac is supposed to measure about 14mm

is not much of a difference so i would say everything is probably alright, my gestational sac was measuring for 6 weeks when i was supposed to be 8 weeks from LMP becuase i actually ovulated late.

gestational sac per weeks:

4 3   
5 6   
6 14   
7 27
8 29
9 33
10   
11   
12   
13   


at 5 weeks the gestational sac measures 6mm, so maybe on her 6 week ultrasound she was actually about 5 weeks aprox

not everybody ovulates on day 14 i ussually ovulated at about day 27

remember pregnancy is counted from LMP (last menstrual period) and if she dosent have a regular 28 day cycle every month she would not be 8 weeks now maybe she ovulated a bit later and she is actually about 7 weeks now.

maybe she ovulated in day 20 or something like that of her cycle instead of day 14.



i dont know why the DR didint explained to you or her that she could just had ovulated a few days later and that everything would probably be ok.

i guess you will just have to wait till the next ultrasound to find out for sure but don't stress to much, i really think everything is ok.

Good luck

at 8 weeks its supposed to be 29mm

im confused

did they did the ultrasound at 6 weeks from lmp or at 8 weeks from lmp????

cause you asked for how much is supposed to measure at 8 weeks but you also said that it was measuring 6.3mm on her 6 week ultrasound???
