the rod

Ok so I got the rod 3 or so months ago and I had quite a lot of spotting in the first month or so and then it stopped and the my last period was about a week ago and now I have it again and anyway a friend said that her sister had the rod and she bled similar to me and 9 months later she had a baby so is that likely like is there anyone else it has happened to? And also is there another contraception that is good for not bleeding and that is one that I don't have to worry about because that's why I don't want the pill because I'm terrible at remembering tablets and things like that so yea anything would help I'm going to get a test just to make sure but yea
