6w+4days twins first scan. Baby B- sac only. Is there still hope?

Had an US today, baby A doing excellent, HR and all. Baby B- a sac only and is one week “behind”- Anyone had similar experience and second baby caught up and did well? I can’t help but think what if baby B implanted later and needs time? I did IVF. Thanks

hopefully if you wait another week or so you will be able to get confirmed if baby B has caught up! 6 wks is still quite early and I suppose if it implanted later then that’s maybe why it’s smaller 😊 will keep everything crossed but congrats on baby A that’s great news xxxx

Twin mamma here. My twin two didn’t show up on the scan until 5+5 after his sister showed up a whole week earlier than him. He measured behind for a little while and then eventually caught up! Xx
