What is the % of survival, kung may SCH ka?

Hello, newbie here....im 5 weeks pregnant and was diagnosed of having a SCH subchorionic hemorrhage.4th day na ako nag medicate..pero ang pag durugo ko ay minsan malakas...minsan naman spotting lang...nag worry lang ako na baka mag lead sa miscarriage. Pero still holding with a Hope na maging ok sya on Oct 2 kasi pinababalik ako for next ultrasound to check if may heart beat at nag develop ung gestational sac.
