yes, 8 weeks can see a lot of things. Yesterday I went to have the first check up at private doctor. The ultrasound shows the heart (it's flashing on the screening). I didn't ask how big the baby is but the doctor said everything is normal. She gave me back the printout of the ultra sound and it shows 16.3mm big. The doctor also found out there is a "water bubble" near the baby. Anyone has this experience? The doctor said some women will have this situation and the "water bubble" will disappear sometime later. Is that true?
