I've gotten so many faint lines this week. I swore It would be a chemical or I was seeing things but then this line showed so quick. Im getting a first response today just to double check.

You can try pink dye as well for checking line progression mine started same with blue dye and currently 16.4 weeks prego

With this pregnancy they got super dark then I lost it. It was faint until the day after period was due.

I know this post is old. But i keep having faint positives😭. How many days were you having faints till yours got darker
