Oh mama, first of all, please try not to spiral too deep into Google, I know it is hard, but the worst-case stories really do not represent every outcome, and your doctor's reassurance that the band is not touching baby right now is genuinely a good sign. From what I have heard, the outcome really depends a lot on where the band is positioned and whether it makes contact with any part of the baby as they grow, if it stays floating freely, many pregnancies carry on without any issue at all. My friend went through something similar and said the earlier they scheduled the detailed scan, the better, because her specialist could monitor exactly whether the band was drifting closer to baby's limbs or face over the following weeks. The concern with amniotic band syndrome is that in more serious cases the fibrous threads can wrap around a limb or even the face, but since your doctor already flagged it and is moving your Week 20 scan forward, you are already in the best position, caught early, being watched closely. Honestly though, I will not pretend there are no scary stories out there, because there are, and I think you deserve to know the range rather than just the reassuring bits, but the fact that your fetus was already well-formed before the band appeared does work in your favour. Still, do push your doctor to explain exactly what they are monitoring at each scan so you feel informed and not just waiting in the dark.
