please help, fetus to small at 8 week ultrasound

[peony30]

I know there have been many threads similar to this one, but I just wanted to ask it again.
I am 8 weeks pregnant with my second child (LMP 21 nov) and I went for first ultrasound yesterday and the baby was not visible on ultrasound - only the gestational sac so they did the vaginal ultrasound and saw the fetus (or is it still embryo?) - and it was 3,5mm big. The gestational sac was good size and shape and the uterus looked good as well. Size of fetus corresponds to 5,5 week long pregnancy - so the doctor said that I probabaly misculculated the dates - the thing is that I am sure of the LMP date and I know when we got pregnant (slow month) so even allowing for longer implatation I should be at least 7 weeks on. They sent me home and told me to come back in 2 weeks time for another ultrasound - is that normal? Shouldn't they do blood testing for HCG to see if its rising? I was told that if the baby stopped growing alltogether they will send me to gynecologist to be examined and given a pill to induce miscarriage.
2 weeks is horribly long and its only been a day and I am very nervous and afraid. I live in the Netherlands (but am not Dutch) and the system here is a bit strange. Pregnancy is followed by midwives and they barely do any testing. I already had problems in last pregnancy - at 8 months baby stoped growing properly and before they could figure out whats wrong I went into labour. The only check up they did so far is ultrasound and I was wondering should I push for HCG blood work or is that not reliable?

Once you can see baby on ultrasound, it's a much better way to monitor your pregnancy rather than BHCG testing. With my third pregnancy , my baby was measuring 1 week small for dates and the gestational sac was measuring 2 weeks small. Baby had a strong heartbeat (160 bpm) so they thought all might be okay. I did end up losing that pregnancy at 10 weeks. BUT, with my fourth pregnancy, the baby measured 1 week behind again and now my daughter is almost 2 months old!!! It's impossible for any doctor to predict what is going to happen, but just try to stay positive, because the added stress doesn't help.

Samething happen to me but they did do blood work they said no heartbeat I'm 12 weeks now and I still think about it everyday that the hospital lied and when I went to my doc they found a heartbeat I'm still nervous I'm on my way to the doc now
