Confused

So AF came April 25th and usually my cycles last about 7-8days, by the 8th day May2 the discharge was dark brown like normal but for the past 5days it still continues, but with a light brownish pink color. I don't know what's going on. I took a ovulation test it was positive, I took 2 pregnancy test and the lines were very faint, I took another this morning the line was still faint but alil lighter than the others. But the discharge is still happening. Someone help me with some advice but I am just too confused....
