Implantation bleeding or regular period ?

Hi guys!!!! So currently I’m on the implant, it’s about to be a month of having the implant. When I got my implant, my period was late for 25 days. But then I recently got my period. Yesterday I got in the morning, it was light at first. Then it got heavy, usually I see clots but I did not see any. Now it’s day two and it got lighter . Usually my period doesn’t get lighter until day 3. My cramps were awful yesterday but now I barely have any. Is this normal ? Or implantation bleeding ?
