Looking for help

I am 7 weeks 4 days. My first appointment is in 2 days. I had some brownish discharge this afternoon (which didnt concern me because I also had it with my first pregnancy). However when I got home around 4 I had some red blood when I wiped after peeing. Not a lot but definitely a little more than spotting. I dont feel any cramps just some slight back pain which I have had on or off for 3 weeks.

I plan to call my OB first thing in the AM (they are closed) but I'm looking for anyone that experienced something similar?
