5 weeks 5 days and spotting

Hi! First time momma here (besides my bonus 2 yr old)! I’m 5 weeks and 5 days. This morning I started “spotting”? I guess the term is? But I’m still so nervous and don’t have health insurance yet as my work is taking FOREVER to get us in the system. This morning, it was only when I wiped and it was light pink. A few hours later, its now a brownish color and enough to get on my underwear. What could this mean until I get an ultrasound hopefully soon. 😩 SO worried but trying to assure myself to not worry and maybe it is just spotting, which is common.
