Getting a BFP later in the day than first thing? Normal?

[babyboybluex]

I'm 11dpo and just testing again after a chemical last month.

FMU (7.30am) I got the faintest of faint line (cheap strip) so did a FRER and again the faintest line.

Just taken another cheap strip and I can see the line a lot more clearly.

This happened last month where I was getting strong BFP's when I tested later as opposed to first thing. Is this fairly normal?

Always same for me. Especially if you pee lots at night I think. HCG builds up over time so it’s not as simple as “FMU” always.
