so every other day Ive been testing since i havent had a period after my miscarriage May 15,2017 ive ive gotten negatives. Today I took one and i have line eyes and my house is dark a bit i thought i seen a light pink line. It was at almost 10 minutes and after looked to get darker a bit. This was a ucheck pregnancy stick test. 
Could this be a positive or and invalid evap test?
