I'm 9w3d and still freaking out one of the twins is going to vanish. We've had 3 u/s where we've seen/heard the heartbeats and they've been within a day of each other in terms of growth. Our RE just released me to my OB after our 8w3d scan and I don't have another appointment until 10w5days. My worry is only increased by my symptoms coming and going. So multiple mommas I'm wondering when your doctor told you you could stop worrying about vanishing twin?
