8 week ultrasound! Advice please!!

islandmommy20 • new mommy!
I had my first ultrasound yesterday, right at 8 weeks! All appears A OK! we even saw the heart rate at 173!!! 
dr did mention some small small hemorrhaging but showed no concern as said its normal. I am of course terrified because I had a miscarriage a few months ago so the word bleeding is traumatizing. 
anyone else have similar experiences!? She said to carry on with normal activity and watch for spotting and call or ER if a lot of spotting or worried. I had. Follow up in 4 weeks. I have anxiety SO bad over this... Help!
