Abnormal test for downs..

Mesha
I just got a call from my drs office saying that my tests results for downs was abnormal.. 😟 My midwife told me the blood tests can throw positive negatives and that they aren't as accurate as other testing... Now I have to go to a different hospital for an ultrasound and counseling on the possible outcomes.. Has anyone had abnormalities with the downs syndrome and everything actually be ok? I'm kinda freaking out right now.. 😓😔
