6 weeks embryo - 5 weeks sac

Hello! Ask ko lang po if may chance po ba na lumaki yung sac ng baby ko? Kagagaling ko lang po sa OB ko kanina and i was advised to have a 2 weeks bed rest tapos niresetahan din ako ng Duphaston and folic acid. After 2 weeks daw po, balik ako to see again if may improvement daw po. Nakaka-worry po kasi ng slight 😞 First time mom here. Thank you.
