Dot putih di jantung

Hi mommies semua. Minta share pengalaman buat details scan sono jumpa dot putih single on left dkt jantung baby. Tp sono ckp risiko sy very low and it will disappear within time being, tp sy nak reassurance yg benda ni normal. Sbb masa scan tu everything look very normal kecuali benda ni, scan 5d pun muka baby sgt2 normal. Passed NT scan.. ada tak mommies2 lain ada experience berkenaan dgn ni?
