Small Gestational Sac, but Strong Heartbeat!

Hi Ladies - Anyone have any success stories of a healthy baby after a small gestational sac and slow rising HCG? This pregnancy has been such an emotional rollercoaster. My doc is now having me come in for weekly ultrasounds to check and see what’s going on. We just went in yesterday and saw the baby measuring 7 weeks, but a small gestational sac, but also a really strong HB. Being in limbo is the absolute hardest. Trying to stay positive for little bean, but my heart is just so heavy! ❤️🌈🙏🏼
