I've missed my period the last month and I am sexually active. I'm 18. I don't use protection but my partner uses condoms. I've taken the pregnancy test (first response to be exact) a few times and I am not pregnant. I didn't get my period, however, I did get a brown discharge that has lasted for a few weeks. I don't feel stressed... what is going on? What's wrong with my body? Lol I've had irregular periods before, but never a consistent brown discharge. Please let me know what you think the problem may be as soon as possible!

The brown discharge is actually dried blood or blood that is "old". If this continues to go on and your regular period does not come, then definitely go see the old doctor as something is wrong.
