subchorionic hemorrhage

I was diagnosed with this during my 9th week pregnancy. May niresita sa akin OB ko na pampakapit and after 2 weeks, nagpa-ultrasound ulit ako and wala na yung Subchronic Hemorrhage ko. Sabi sakin ni OB, usually, hindi naman talaga ito harmful kay baby PERO may tendency kasi itong lumaki and may cause complications. As per her, nawawala lang talaga ito after 2 weeks.
