Had a rough day from baby being measuring extremely small to baby measuring just fine. Cried loads , felt helpless. Hope everything goes well

So today I went in for my 37 week appointment. I was 36 week and 5 days . What happened was that when they did scan they told me baby is 2 percentile and she grew only 5 ounce since last scan. That means in almost three weeks and they might have to look into performing a csection or may be do further test to see what's wrong.. I had stress test right away. And for scheduled for a detailed scan that was 4 hrs later . Those were the longest hours of my life. Turned out thankfully everything's ok and baby is 14 percentile. M much relax and I hope these readings are most accurate one.
