Since the 30th (my 31st birthday) I had strong cramps and twinges. Since then till about March 10th I finally had succeeded the cramps and they got dull. My boobs, were also sore till the 10 & heavy. Today they're mildly sore. I started spotting during discharge since Saturday (10, and today 11) my CM Is dry, like as in I'm not producing any and usually I do a lot before AF. But haven't. When I wiped Saturday after using the bathroom it was very very faint pink and then I had no d/c, today I wiped after the bathroom again it was light pink with a little brown, through the day nothing, it's only light pink now very faint. No blood like discharge. 

My flow is due the 13th. 

My big question is my first signal eats. I started testing 8th to today and they are confusing. All my tests when I come back after an hour have faint positives? Are these common this many days in a row, they all dry different too. I'm new at testing. I've been using opks and even those I'm new at. 

Any advice whether they're evap lines or indent lines would help. I'm not hopeful but trying.
