Anatomy Scan take 2! First baby and she is our suprize baby.

So I had my anatomy scan on the 27th and was told that the cord only has 2 arteries instead of 3 but baby girl is growing just fine. However my high risk specialist informed me that she saw a curve to the spine that was abnormal and shouldn’t be there, she said for now we are going to hope it was the way she was positioned and I will go back on the 17th of this month to take another look. The dr wouldn’t say what this could mean because she didn’t want to worry us if it was nothing. Needless to say I’m worried. I have high blood pressure and gestational diabetes that I have to take insulin for, I see 2 drs already and one every 2 weeks. I’m trying not to stress but it’s hard not to worry. This is our first baby and according to drs we were told our shot of conceiving would be about like winning the lottery so she is our little miracle.
