TOOK A MORNING TEST

So I used morning urine this time and the very faint line appeared ONCE AGAIN.. It appearead within a min or 2. Could this mean I'm very early in the pregnancy? Since yesterday morning I been letting out very light pink/brown discharge I've had headaches non stop. I get somewhat tired during the day. But one thing that made me take this test was my mood swings lol I've been having alot of those.. I feel like I can't stand anything. And according to my calendar I should be getting my period tomorrow.
