In my past pregnancies I think I had mine at 24, 26, 24 and 22 weeks...if I have one this time it will likely be the same! So I get to wonder and just assume things are OK. If they can quickly pick up a heartbeat on doppler at 12 weeks I might consider that.
i know this thread is old now, because i got a late ultrasound and i'm due at the end of the month, but i'm just so excited to show off my lovely little person. 10.6 weeks by dates, but measuring 11.4 on the ultrasound. baby was still/sleeping for most of it, but finally at the end started kicking around a bit which made me happy. and i heard a great heartbeat. after 11 weeks of worrying about miscarriage, i can finally relax.
Congratulations! I'm sure that feels great, knowing everything looks OK!
