Blood spots in uterus?

Nikki👼🏻👧🏻👦🏼👼🏻👼🏻👼🏻👼🏻👼🏻

I had a viability scan today(I’m 5 weeks 6 days)which showed a baby measuring 6 weeks and 4 days WITH A HEARTBEAT! Heart rate was 117 but she did mention blood spots but didn’t really say what that could mean. Of course I googled it and mostly saw worse case scenarios. She wants me

back for another scan on October 2nd…so soon and it has me concerned.

Does anyone happen to know what the blood spots could mean?
