ICEF at 20 weeks

As

at my 20 week anatomy scan, the doctor told me there was a white spot on the heart. which is ICEF. intracardiac Echogenic focus.

calcium buildup.

has anyone had this?

I'm being sent to a fetal specialist but not until the 28th of this month.

I cant help but worry and wonder.

also, my baby is measuring small. (12oz.)

but he's measuring at exactly 20 weeks.

I am 26. I was tested for down syndrome via blood draw yesterday, to rule that out.
