Implantation?

Chloe

Confused???

I took many ovulation tests when I was expected to be ovulating but all came back negative? my period is expected in a week but I’ve been now I’ve started to get really bloated these last few days, very saw and tender breasts, cramps started earlier on today and still have them now! I have also started to bleed very lightly in a pinkish colour! is this implantation?
