Confusing story

So June 18th had my period it lasted two days which is kinda normal for me...well after it was gone I had light tan discharge only when I wiped for at least 10 days then started my ovulation week I got a positive ovulation test on June 28th but I was having really bad heart burn all week which isn't normal for me just on a whim I took a hpt on Saturday and got a faint line I was confused I also had a bit of ewcm..well I took another test Sunday and the line was a bit darker...but now nothing I'm also getting positive ovulation tests again and I'm supposed to be 6dpo today...any feedback..
