Hey there. Looking for a little info and maybe good news?! I just found out I'm pregnant with twins after <a href="https://glowing.com/glow-fertility-program">IvF</a> but in the first US (6w5d) we saw two strong heartbeats and yolk sacs for each but baby B's gestational sac is measuring quite a bit behind A. The CRL size for the babies are almost identical. My RE was concerned about the sac size and said it's a wait and see. 

Just wondering if anyone went through this early on and what the outcome was?? 

My RE said if either were just single babies they wouldn't be too concerned but the comparison makes them leery. He said 80% good, 20% bad. But being an <a href="https://glowing.com/glow-fertility-program">IVF</a> pregnancy, we're usually on the bad end. Hoping our luck has changed!
