Line progression?

Question

So the bottom was yesterday morning. Top was this afternoon. Looks good but I hope it’s not twins because that’s significantly darker in 36 hours

Answer

Line darkness has no correlation with twins

Answer

Update: it is twins

Answer

It’s not even the same tests.. how can you compare? Each test registers a different amount of HCG..

Answer

if you're gonna do progression best to do it with same test as same times if day.. here's mine  for example xo

Answer

top is darker because test is more sensitive.. congrats
