implantation feel like early SUPER light period?

Never had implantation with any of my four pregnancies, but this time I feel like the timing may have been ideal to conceive when ovulated 7 days ago. 
Had tiny dots of bright red blood two nights ago then cramps to follow for a couple of hours. 
Then had same exact thing, except it was old brown blood dots with cramps to follow.
And today a little bit more brown blood.... with light cramps on and off. 
Period not due for 11 more days though?! 
Please comment any experience or kind helpful insight.
Be blessed-
