Implantation bleeding

Katie • Hubby and I are expecting our first child together in March!
My period is due in a week and today, I had a little spotting. I had a miscarriage in April and my last period was 5 days late. Last Saturday, I took an ovulation test and it was 100% positive. My question is, would it be too soon to have implantation bleeding, or is my period going to be early this time? Trying to stay "positive" pun intended.
