Subchorionic hemmorhage

Hi everyone! So I had light pink spotting Friday night, then brown Saturday morning and then back to pink. I never had a spot on my panties just when I wiped, so I ended up going to the ER for an ultrasound to make sure everything was ok because I had bled moderately about 2 weeks ago. I'm 5 weeks and 3 days. After spending 7 hours at the ER I was diagnosed with a UTI and a small subchorionic hemmorhage. The doctor didn't tell me a whole lot except to follow up with more blood work at my OB tomorrow but not to worry about it. It's kind of hard not to worry though. Has anyone else experienced this?
