Wa'alaikumsalam wa rahmatullahi wa barakatuh sis! This is something you really need to discuss with your doctor or OB-GYN as soon as possible, don't wait. Two sacs but only one with a baby visible at 10 weeks needs proper scan assessment and follow-up, because only they can tell you what's happening and what to do next. I know it's scary, but your doctor is the one who can give you clear answers. Sending you strength, ok?
