Mid cycle bleeding/spotting? (Tmi maybe?)

Ericka
I've been having tailbone/lower backaches &a headache for like 72 hours and once yesterday I peed and there was some blood, none on my panties though and barely any on the tissue. Same thing happened twice today. Af due 9/15.. I'm not sure if this would be considered spotting or not... what else could this be?
