Hello - I had an early ultrasound today because of some spotting - I’m 6 weeks exactly. The sonographer found a gestational sac, yolk sac and feta pole, and thought she could detect a heartbeat. She also said there was a second yolk sac, but she couldn’t see a fetal pole.
The way she spoke about it was that this had been a twin pregnancy - and seemed to suggest the second yolk sac wouldn’t develop (I didn’t ask the question directly as I was a bit shocked).
Is it likely that if one of embryos has a heartbeat at this stage (and is at least visible), that the other is not viable? (I’ve heard of vanishing twin syndrome). Or could it perhaps be that it will develop, but it’s so early right now it’s hard to tell/couldn’t see enough? I suppose what I’m asking is if there were two would their development be identical?
Any experience of this welcome! Thanks!
