Evap on a tweak?

Rachel
I'm posting this in "General Pregnancy" because I figured there might be more people that know....
When a test in tweaked, does an evap line show in the tweak?
I took a test this morning and didn't dwell over it when at 3 mins it looked like a bfn, I let it go and went on about my day. My dh found it later, and swears it's positive, but it was well outside the time frame. There is a bit of a pink tint to it, but I'm still unconvinced. I tweaked it, and the "faint" line shows on the tweak....
So my question is, do evap lines show up when tweaked?
