Hcg doubles every 48 hours. So you wouldn't see much difference in the darkness of your lines in less than a full days time or even a day !! It looks like it may be a tad bit darker though. Good luck fingers crossed for darker lines with tomorrow test hun !! Congrats !!
These tests are tricky!! It looks like it could be darker but not much, I’d wait a couple days! Then you’ll really see a difference or try first response for a more clear line ☺️☺️
