TMI- 6/7 DPO

Ma

I don’t want to get my hopes up.

I had a peak positive clearblue advanced OPK on Thursday 3/15. Today is Friday 3/23, so I think I am 6 DPO. Anyway, I’ve had cramping ever since 3/15, yesterday I had a bad headache and today I had lower back pain. Today I had dark brown discharge. I feel like it’s way too early to be my period right? Is it possibly implantation, or something else?
