    when is the earliest you can have a dating scan?

    Hi All
    I got a BFP on Tues and I am off to see the Dr today... YAY YAY YAY!
    I have to book in for a dating scan, when is the earliest this is possible?
    I am impatient and want it asap - then this will all feel real. Think with DS I was either 6 or 8 weeks... cant remember though! tia

    heartbeat generally doesn't start until fetus is 5w3 or 4d - so LSK's scan at 5w might have been a bit later but baby measuring small. they're so tiny at that point, that they tend to have up to a one week window of error

    as a rule, most places wont' scan until at least 7 weeks as the baby isn't big enough to see anything on an external scan at that time. i know of at least one BB-ite who was told they had a 5w sack, come back in 2weeks to check viability. it's better to wait a bit longer...

    OMG you fertile thing.....congrats hon !!!

    I didnt know with this pregnancy or last one when i was due , coz of b/f and no AF.
    After i got bloods with Sam (which showed HCG at around 5 weeks) i just timed a dating scan for 3 weeks later, so at 8 weeks. You would have a rough idea when your due wouldnt you ????

    I had one at 8wks....still looked like a little alien, but was so good to see what he/she looked like already!
    I've had 4 scans in total and it is just glorious to see how much he/she has grown since the last one
    8wks dating scan
    12wks nuchal screening
    19wks morphology screening
    30wks growth assesment

    Not long now!

    Preg - I'd go 8wks for a couple of reasons. If you are not as far along as you think then at least you'll still be around 7 wks and they can see clearly at that stage. My doctor recommends 8wks because it is a good time for accurate dating. Going any earlier can be disappointing if they can't see much.

    i had one at 6 weeks and they could not see anything but a sac, so of course i freaked and thought straight away 'blighted ovum again" ....but all is fine!!!! i wouldnt go before 7 weeks just to be sure that there is something to see.
