So you got your 1st bfp at 12dpo? I got 1-2 wks on digi at 10dpo, 5 days later @15dpo 2-3 wks but only with strongest sample 2nd mu. Back to 1-2 wks later in day same at 16dpo. I got 1st 3+ at 18dpo but went back to 2-3 wks til 20 dpo.
What I am trying to say is, you got bfp a couple of days after me so don't go exactly on anyone else's land mark days for it changing if that makes sense??? Also and more important, yes the digi shows a general increase in hormone. But these hormone changes are so subtle in the early days and so easy to influence by drinking holding pee even how long you dip stick for. With mine they were back up and down for a couple days before settled at higher level. I was like you chasing the wks as with my 7wk mc I never got past 2-3 wks. I think what's more important will be if you am manage to wait 4 or 5 days and do another digi with your best sample if day, then see if it increases??
Hope this makes sense????
Also as far as ic.... They do not progress very much at all. I ran out about 2 wks ago and mine were still only just as dark as the control and scan that say showed all well. I drive myself mad doing frer and comparing progression to everyone else on google at same dpo. Totally pointless. What I should have taken reassurance from was that for me, the tests were slowly progressing over time. Even with the odd one thrown in that looked fainter!!
Sorry I rambled!!!!! Just know exactly where you are at the moment flower x x x x x
