Confusing test....

Ryanne

Anyone here have experience of accumed test? So for the past couple of days I have been taking accumed ic, and there have been shadow lines on all of them....however this morning I took one and at about 10 min mark there was a faint but there positive so I snapped a picture....I went back to look at the test 45 min later and the positive line is gone....I didn’t over saturate the test or anything so I’m confused.....any advice???
