Discharge which looks like dried blood.

Hidalgo
I am 7 weeks 2 days pregnant with triplets. Ive had 2 ultrasounds done. Their sizes and heartbeats are what they should be. But just now I had brown discharge which looks like a discharge of dried blood. I've had no bleeding or spotting upon conceiving and until now. I'm calling my doctor tomorrow. But I wanted to ask everyone if they think this should be concerning. The discharge wasn't heavy, just a couple spots so far. Please let me know if you have any insight on what might be going on. Thank you!
