Tmi discharge Don’t have and idea what Im wiping and whats with my bbt

So Im on CD34 10dpo. I started wiping brown for 3 days now but its only when I deep wipe, wondering if its my cervix? after I had my baby girl all my cycles start heavy immediately never wipe light. My cycles are usually 30-34 days. Not sure if Im wiping brown discharge or just old blood.

Please let me know you’re opinion and if you had something similar what was you’re outcome..

Im 5 months almost 6 months PP

Yesterday’s afternoon I wiped this

Before this I was wipythis
