[|Human|] I had an ultra sound at 4 weeks 6 days and nothing could be seen, just 3 small dots. I had another ultra sound 1 week later at 5 weeks 6 days and they only saw a very small gestational sac measuring at 3.51mm. The dates are exact because i had an IVF so we know the exact date of ovulation. Everything I read online says that by 6 weeks my gestational sac should be at 14mm, but mine was only at 3.51! Does this sound like I may be in for a miscarriage?
[|AI|]  HI, I understand your concern.  Average size of gestational sac at 5 weeks is 2-3 mm.  After IVF assessment of the embryo size with USG alone is not considered reliable blood Chat Doctor levels are more confirmatory . As proportional Chat Doctor levels with trans abdominal detection of an embryo is sufficient to assess pregnancy by IVF in early weeks.  Please don't worry follow your doctors instructions & be positive.  Thanks.
