Is it possible for an ultrasound to be way off? The first one they gave me placed the pregnancy at 6w1d, that was 2 weeks ago today. I'd be 8w1d. The second, they said I was 6w5d so I'd be 7w5d. Today the obgyn said I was 6w6d. That's impossible. I would have had my BFP at 2w5d. It's impossible! But she said the heart had a good beating and that everything was good, so I don't have a follow-up ultrasound. What does everyone think? I'll add the progression. It started off as a yolk sac, then a small, round fetal pole, and today we saw the head, body and spine with a strong little heart ❤️ I'm just freaking out about dating much earlier than I thought (I'm pretty sure I'm 7w6d, which means I would have gotten my BFP at 3w5d. Makes much more sense!).
