Is that big and Subchorionic Hemorrhage at 19w

I have a Subchorionic Hemorrhage at 19 weeks measuring 5.7 x 1.7 x 6.2 cm and me being the math wiz that I am (sarcastic😂🤦🏼‍♀️) doesn’t know how big that is. Anyone had one this late in pregnancy and was fine? My baby is perfectly healthy otherwise :)
