Hi there, i did this test in work and didnt notice anything so put it in my bag as i was in a rush and nearly finished my lunch break. I took it out to throw it in the bin about 45 mins later and noticed a dark blue line. Is this an evap line or positive? I have PCOS so periods are all over the place and dont know when i ovulate, thinking its too early to test but just needed some advice! Not currently TTC but not using protection, thanks ladies
