Nexplanon spotting?

Lilly

I got Nexplanon put in at the end of February, no problems for the first few days but then I started my period and it lasted for about 2-3 months. In the beginning of June it finally stopped and I haven’t had a period since. Until tonight. (2 months)

It looks like period blood but it’s a super light. flow.

Could this be implantation bleeding or is it just spotting

I feel like I’m over-thinking it but I would like a second opinion.

Thanks.
