Brownish/light bleeding from time 2 time and breast tenderness....what could this mean?

im 18 and sexually active with my boyfriend. for the past week ive been having this brownish/light bleeding(once in a while) discharge and breast tenderness. I did get a light period the first week of may. I took a pregnancy test yeatserday and the test was innaccuarate could this possibly mean im pregnant, have an ovarian cyst/cancer, or an infection. i'm going to set up an appointment tomorrow and just wated some feed back for my own knowledge.

Hello,

I just read youe qoute there i have been treated for having thrush just 3 days ago but ever since i have been treated i have been bleeding its kind of a reddy brownish colour im quite worried about it as my periods are at least 2 weeks away. If anyone out there has any idea whats goin on let me know.

Thanks
