Hi, I m 40yrs old pregnant with my third child. Originally I was pregnant with twins at 15 weeks Baby A passed away. No reason to why it was growing normal, Baby B is now 17 weeks an 5 days development is on target. I m high risk an being seen by fetal medicine, seems like every time I go there they have so sort of bad news. Today through ultrasound they say that baby B has echogene bowel, a bright spot on her belly an something about a third bone not being in one of her pinky fingers. Soft markers for down syndrome , he did say that being as baby a passed away baby b could ve swallowed some blood . How could that be? Everything else with her is fine, she has a nose bone, the sack behind her neck is normal. Could this all being coming from the death of baby a? Thank you..
