does this sac in the ultrasound look okay? is the tiny white dot the beginning of a developing yolk sac? As we was watching and she was moving the Doppler around we saw a faint white line but from different angles we would then see this white dot appear at certain angles, Been having a scan weekly due to bleeding around 3 weeks on/off that lasted a week, it was then suspected possibly miscarriage / collapsing sac when I had my first ultrasound 2 and a half weeks ago, but I’m guessing it’s because they couldn’t see much on the scan because I was a lot earlier than we thought as I’m only now 2 and a half weeks later only 5w4d. So this looks reassuring, doctor said today not concerned of a miscarriage now as it seems to be developing and progressing, my hcg levels are rising not quite doubling but are rising, still hold a lot of fear and anxiety due to the doctors suspected “miscarriage/collapsing sac” but this looks a lot more progressed and clear than my previous scan a week before which is shown (second photo)
