TWINS 8wks & 5 wks

Hello mommies, i just had my first ultrasound today and nakita na twins, pero si twin A 8 weeks na and malakas heartbeat while si twin B 5 weeks palang and no heartbeat. Possible pa po kaya na magprogress pa si twin B? Meron din ba sainyo nakaexperience ng ganito? Thank you mommies and prayers to you all 😊❤️
