Mono/mono twins anybody?

Nicole • Married to the most amazing man on 9.28.14, had identical twin girls on 3.14.16, now expecting number 3 in May!
Was at the doctor and they can't find a line indicating a second amniotic sac so on October 5th we're getting a higher resolution ultrasound to find out... I already made the mistake of doing research. This picture was taken at 9w5d. Almost 11 weeks now. Any mo/mo mom's with reassurances? My husband and I live almost 6,000 miles away from family so kinda worried.
