Umbilical Cord only has 1 artery.

Kierstin

Apparently typical umbilical cords have 2 arteries and 1 vein. my baby's umbilical cord only has 1 artery and 1 vein. Apparently this can affect the baby's growth. right now baby is in the 40th percentile for her weight. is this good!? has anyone else experienced this complication in pregnancy!? I'm FREAKING OUT
