All screenings came back negative and still miscarried

Cl

Hi all, for all those women out there who have experienced a loss and are pregnant again you know the struggle of the worry and stress over the new pregnancy. I am currently 17 weeks and because of my age and prior miscarriage they had me do the the genetic testing at 12 weeks for Down Syndrome and Trisomy 13 and 18 and the blood test at 16 weeks for all the nurel tubal possible issues including spinabifata. All these tests can back low risk. We also had the scans where everything looked fine. My question is are there people out there that did all these tests and still misscarried/had a still birth? I'm just wondering if there is ever a point where I can stop worrying!?
