has anyone has implantation bleeding?

my period is not due till august 2 I'm on my last day of ovulation and today sorry for (TMI) I went to the bathroom and it was really light and such a small about of dots of pinkish blood when I wiped. is that too soon? I thought it was weird to see real little of blood and hard to explain boobs reallt hurt as well. we have been trying for 3 years and get my hopes up before every period then nothing.
