9DPO implantation ???

I’ve been feeling really emotional and bloated and nauseous for a couple of days now... Today I decided to test and got a BFN... then later on I was standing and left this sharp pain on my right ovary side it was like a pull or pinch can’t really describe it because it was just one time then as I’m laying down I feel little cramps, my boobs have been super sore which is not normal for me when I get my period they usually never get this bad put

Could it be I’m just now implanting or am I just getting AF??? 

Anyone else Experiencing this?
