sorry if this is gross, but this came out of me tonight. I don't have a damn clue what this is and I am scared http://i.imgur.com/K7O34zU.jpg
Brown blood is just blood that's been up there longer than the red blood. It could just be hormones that caused the problems (thyroid, estrogen, etc.) or a change in diet/exercise routine that was extreme or stress or illness or a myriad of other things. Glad to hear you're planning to go in!
Yeah, I am planning on going Monday. I just don't know what it could be now that I am bleeding. The blood is ranging from ruby red to brown, so I don't understand why it's doing that!
A pregnancy test should be able to catch an ectopic pregnancy as your body still has to signal itself not to have its period by creating Hcg. However, you may want to go to the doctor just for an exam. The reason for your lack of a real period could be many different things.
