6dpo or 7dpo or 8do brown discharge

Not sure what the hell this is peeps. Not sure when I ovulated neither. But its between 6dpo and 8po... I'm so confused. No other symptom except cravings of sweets. And I dont eat sweets like that.

Lol can someone please tell me what this is? Also every now and again I have light cramps and weird sensations in pelvic.
