8 weeks 2 days Pregnant with Twins, SCH

Good Morning Mommies to be... I am expecting twins and I haven't had many pregnancy symptoms besides going to bed really early. I am due July 8th can anyone else relate? I seen both babies on the ultrasound with great heart beats, unfortunately I was diagnosed with Subchorionic Hemorrtoma at the ER I went in for brown spotting. I go back to my OB in two days to see if it's decreased or increased in size. Does anyone have experience with Twins, Brown spotting or a SCH?
