Misshapen Gestational Sac

EJL
Has anyone had any experience (good or bad) with having a misshapen gestational sac? I had an early ultrasound today due to issues I had in early pregnancy with my daughter and my doctor seemed a little concerned that the gestational sac isn't round (more oval shape). I'm only 5 weeks, 4 days so she said it's still too early to tell what will happen. I go back in a week to see how things are progressing 😕
