Sayang, this is really something you must discuss with your doctor right away , jangan tunda! Two sacs dengan size berbeza besar and spotting kena monitor closely. Please book an appointment or go to clinic/hospital hari ni kalau boleh, ok? Your doctor will do proper scans and blood tests to check what's happening, ini bukan something yang boleh assess online. I know first time mom memang scary, but the right person to reassure you is your OB/GYN. Sending you hugs, do update us after you see the doctor, and take care of yourself in the meantime!
