Subchorionic Hematoma :(

Dee • DD2 born 5/18/15 @ 7:30am, 6ibs 13oz, 20in
Went in for my very first ultrasound today and tech found a "small" subchorionic hematoma. My doc said for me to go in for another u/s in 2 weeks. 
Baby's heartbeat was strong. I'm currently 12weeks+3 but measured 11+4 today. I think I just ovulated a week late. 
Anyway, anyone in the same boat??
I've been googling like crazy and there were many assurances that my baby would be fine.
Please pray for me. 
Thank you.
