Hi there! I'm 15 years old, healthy, active and gay (so no intercourse or sexual activities whatsoever so far). For about 3 years now, I've had a very irregular period. Since the beginning of my periods actually. The space between them canrange from about 54 days to almost 4 months and when they come, they are usually accompanied with a deep brown colour (old blood?). It also has a foul, fishy odor. As stated before, I am not sexually active and have no health issues besides enthesitis-related arthritis and anxiety. Could this be from my anxiety? It's definitely not from my arthritis medication, because I have been this way even before I was diagnosed. Any help would be appreciated. Thanks.
