Twin-to-twin transfusion syndrome (TTTS) is rare and results from disproportionate blood supply between two (or more) identical fetuses that share a single placenta. One twin, the donor twin gives away more blood than it receives and has a risk of malnourishment and organ failure. The recipient twin receives too much blood and risks overworking the heart and other cardiac complications.
Currently pregnant
Rapid increase in abdominal circumference (waist size)
Feel my child is moving less. (Decreased fetal movements)
