Bloody CM before ovulation?

I’m one year post partum, still breastfeeding, and I’ve had a regular 30/32 day cycle for about 4 months now. I’m suppose to ovulate In about 3/4 days and I’m having some bloody cm when I wipe and a little in my underwear. It’s darker red/brown blood. Does anyone experience this before/during ovulation? Or should I be concerned?
