Do FRER indents get dark after drying?

I am getting some pretty clear + on blue dyes now. Not squinters. They are blue and getting darker. But FRER are looking very faint. But after drying there are lines there. Can anyone show me a light dry actual positive on a FRER? I don't want to get too happy and be let down. I have more FRER going to take within next hour. Also have a FRER and Clearblue digi that I am holding on to for another 3 days. AF due in 2 days. I don't know how many DPO I am. Had sex Feb 12-16. Brown spotting light a couple days March 1st and actual noticeable blue dye + with color yesterday
