16dpo Lines- should I be worried?

[PizzaPartyForOne]

Just looking for some advice please! I tested positive on Sunday at 13dpo with the line in the first picture, yesterday i had a positive clearblue 1-2 result.
today I have done the pink test below and am worried that it is fainter or not as strong as it should be for 16dpo??
Does anyone have any idea if this looks okay or should I be worried? I haven’t done this before so don’t know what I should be looking for!

I’d really stop testing. My tests actually got lighter at the beginning and I’m now 27 weeks pregnant. There’s too many variables that can affect how dark a test is. I used fmu thinking it would be more accurate but still got lighter lines. Caused so much anxiety.
