Could this be implantation bleeding ?

So about two months now I have stopped trying. I stopped temping, opks. I mean everything we had sex just one day in what I thought could be my ovulation week but who knows. Anyways thursday I had light spotting then it stopped. Friday I had some very dull cramps off n on, also my breasts r tender and I’m very moody. Then at work tonight I had this light pink spotting then nothing after that but some dull cramping again. Idk what to think my period is due in 7 days . Help please ladies?!?!?!?
