This might be a dumb question lol....

If I have held my pee all day (7-8 hours) can i take a test at night and it be about as accurate as taking one with fmu?

I took a cheapie blue dye test this morning, and the positive was SO faint, like i could see it but i had to turn a picture of it negative for it to even show up at all in the picture i sent to my boyfriend.

I had to leave for work shortly after, but since he is bringing home some of the first response early detection ones, i avoided peeing at work in case it might help a test read more accurate tonight. I’m so impatient and quite honestly losing my mind, so i’m wondering if it would be worth it to take one at all tonight or if i should just wait all together.

I’m 5 days from my expected period start day & about 10dpo.
