To be honest, i wouldn't stress about it. Your progression looks great. And you can stop testing now. To me, it looks like thats the darkest the lines may get with that brand. Congrats!
Thank you so much for the reassurance. I’d never considered that this might be as dark as the line gets (it’s a 2ssan and previously I’ve used FRER).
I experienced hook effect around 13dpo and NEVER had dark lines. Line progression means nothing! Take it from someone who tested everyday until she was 12 weeks, it isn’t worth it! If you have betas, wait for those and for now bask in the joy of being pregnant (easier said than done i know). Biggest congrats!!!
I would definitely not over analyze this! These look great! Time to stop testing now or you’ll just stress yourself out. Which is actually worse for you and baby both.
