I have had the same problem with brown spotting, I get my period then nothing for a week then spot all the way up to my next period. I am only 16 years old and it hasn't been going on since my period started (which was when i was 11). It's only been happening for about fro months. I haven't had sex yet and thus have not been involved in any pregnancy, miscarriages or abortions which seems to have been a trigger for some of the others here. I am already annoyed that this has been going on for 4 months I can't imagine this continuing for 8+ years. I have tried to figure out anything that could cause this. I'm scared, confused, stressed and i too suffer from anxiety. I hope this wont be underlooked because I'm young and haven't been experiencing this for long. I just want to know what is happening.
