At what point should line darken?

[bitheby]

Sorry. This is my first time TTC.

I'd had two positive FRERs, yesterday and day before and this morning I did a CB Digital and got Pregnant 1-2.

All good. But I thought I'd do a FRER so I could see line progression but the line isn't much darker than yesterday.

At one point should I see a nice dark line?

First photo shows all the tests. Second photo, today's results. Is that about what I should expect?

First day of missed period is today.

Sorry photos are a bit rubbish. I woke up really early dreaming about work and I'm not really awake yet.

Every three days as that's the time it takes for the hormone level to double. You won't see a clear difference day to day.

I always had a much more distinct positive the day my period was due but everyone is different and you may have your dates wrong. Just be aware that frers and clear blue digitals do pick up chemical pregnancies. Happened to me 4 times before I got a sticky one

Thank you @BrooHaHa

That's what I needed. I'm not getting carried away. It could be a chemical or end in miscarriage. I was just hoping this morning I might get an indication that this is progressing as it should.

I'm 43, TTC#1 with a donor. If this doesn't stick, it could be months before I can try again.

They look like good lines to me but I'd say you would get a darker one in about a weeks time maybe.
Congratulations by the way!

Thank you. I really need to dust the top of my toilet

I would get a some other tests than a frer. I got darker lines on cheaper tests. It looks very hopeful

I always have darker lines on cheapies even with afternoon wee.
I also did a frer with fmu, then another one 4 days later and it was much fainter:o of course I worried.
Did another cheapie strip day after and got a blazing red line.
I left it at there! Haven’t tested since.
