line?

the line came within the time frame but is really thin. husband says he can't see it and that makes me feel crazy. I know there is a big possibility that it's a evap line or whatever. I'm hoping it's the start of something. over the weekend I have had faint lines on the 88 cent cheapie test. also posting those. But the question I have is has anyone ever had a thin line like that and it was legit. Also, has anyone ever had faint positive that grow darker as they dry and it was a BFP. I pray for all those woman along this jurney who are ttc. Thanks in advance ladies hope baby dust to you all.
