Difference between spotting discharge and light period

Be

Ok so can someone tell me the main differences between:

Brown discharge

Brown spotting

Brown light bleeding

Because I’ve been what I would call spotting for 4-5 days but doesn’t go into a pad only a little bit when I wipe, it’s always brown

I’m 8 weeks post D&C and I haven’t had a period yet but to me I wouldn’t count this as a period so just wondered how you girls would tell the difference between those three things
