Evap/indent

Carissa • Trying to convince bby #1 ❤️ mommy to an angel 216👼🏽
Might be a stupid question but do evap or indent lines get darker ? I've taken test all week (testing early) and the line has gotten darker but not enough for me to say it's a clear positive . I'm 4 days away from AF and don't want to get my hopes up to soon.
