Very confused, help?!

So I had this last week and thought it was the start of AF, but nothing else happened apart from brown cm???

My cycles are all over since coming off birth control in May. I had the implant which stopped my periods altogether but I actually haven't had a period since having it removed, I just don't know what to think!
