Faded line the day after BFP

Hi Ladies,

I took a test yesterday morning (FRER) which was a bfp result with a light line (but definitely there). This morning I did another frer but the line was almost impossible to see…

I did have some water last night (only a pint) before going to sleep - is there a chance that I’ve diluted my wee? I’m so confused as to what this means 🫣

I wasn’t actively TTC so I don’t have exact dates (if I go off my Flo app - which I’ve only had a couple of months so not sure on the accuracy) I’d be 14dpo today.

AF would be due today but nothing yet, just looking for some positivity please and any success stories/insight 😌
