Calcification on baby’s heart?!!

So today i has my anatomy scan at exactly 20 weeks pregnant. And the tech found something called 2-3 spots of calcification on baby’s heart. Everything else looks pretty normal. Very normal growth of baby and other organs. Baby seems to weigh around 12 oz. doctor said its probably nothing to be worried about because she didnt find anything else wrong. But still she suggested i go for genetic testing. And also referred to me a specialist doctor for fetal medicine. Im freaking out. This is my second baby. My first one was very healthy. No problems during or after pregnancy or after she was born. No genetic disorders on my or my husband’s side.

Has anyone had this problem and turned out to be ok? The results of genetic testing will come back in about 2 weeks. Doctor said to me again and again that dont loose your sleep over it. Its probably nothing.

This pregnancy is being rough so far. First i was diagnosed with partial place previa because i was spotting. Kept spotting continuesly for first 16-17 weeks. Thank God its resolved. And now this...
