Period or withdrawal bleeding?

As

On monday 24th I starting bleeding until friday 28th. I noticed it when I wiped. It started off light, then heavy, then light again. It ended with some very dark brown blood/discharge. I had the implant removed around 5 weeks ago. I haven’t had a period since having the implant fitted 3 years ago. I have been reading about withdrawal/breakthrough bleeding when you have the implant removed. I am trying to conceive and wanting to track when I am ovulating. So wanting to know whether people think this bleeding is a period of withdrawal/breakthrough bleeding?
