My last period was Aug 30 . It's now almost 2 mos with no period . I've taken 3 pregnancy test . 2 of which a faint line appeared AFTER the time frame so didn't think nothing of it . And on the last one I couldn't see anything I don't think . Only symptoms I have is super sensetive boobs and cramps in my lower abdomen . On cycle day 50-54 I notice brown discharge but only in morning and not a lot  . Just don't know what to think . Any advice helpfully....
