Only evap ever and has color. Possibly leading up to BFP?

So this is outta the time frame by a lot. The one at the top is older than the bottom one. Never had a colored evap is it possible that it may be a sign of a BFP soon? The test line/evap is thin but there. Pregmate brand. Its the only evap line that ive gotten ever and it has a little color. Just need opinions!
