Spotting?

What is considered spotting? Im about 4-5 weeks pregnant at the moment.. I’m not bleeding to the point where I need a pad (it doesn’t get on my underwear or clothes at all). Only when I wipe, but when I wipe it sometimes covers the all of the toilet paper. It looks like a period, honestly & is pretty much the same color. I’ve been spotting/bleeding like this for about a week and a half.. does this sound like something normal, or a miscarriage? The doctors really don’t know & I’m not scheduled for an ultrasound until the middle of the month. Thanks in advance !
