can a FRER produce a PINK Evap?!

I had to take it out because I thought I saw something but the screen was like glarey. I also have a similar faint blue line on a crystal clear test but know pink dye is more reliable. I haven't posted pictures of blue test but both were taken with FMU (the same cup of urine used for both tests)
I did these tests this morning, I am on CD 44 and my cycles are normally 35 days. I had a blood test at 4:30 yesterday but don't get the results until Monday so trying to decide if I should buy a digital tomorrow or just wait ?
