Lines getting lighter?

[DriftGames]

Found out I'm unexpectedly pregnant last night and unfortunately I plan to terminate (lots of reasons which make sense for my family).

I've taken 3 tests, all with fairly concentrated wee (contact napper DD makes me wait!!) and they seem to be getting lighter. Can anyone else see this? What does it mean? I'll continue to test at the same times for a few days to monitor but wondered if anyone has any experience with this. I'm about 4 weeks, no symptoms whatsoever.

OP I’m sorry to hear about your tricky situation. I don’t think those lines look significantly different enough to draw any conclusions at this stage. Maybe test once a day for the next few day?
Wishing you all the best.

@Rhubarbe Thank you, I'll do just that to monitor, however I'm having a scan to date the pregnancy on Tuesday and will go ahead with the termination at home later in the week. Thanks for your help & sympathy
