When can I test with mid-day pee?

Hi. I have to get up to pee several times a night (always, not just during pregnacy :s ) so if I try to hold my pee all night, to do a hpt with my 'first morning urine' I get absolutely no sleep. :( I was wondering how may weeks from my last period I have to be before a hpt ( I believe mine are 25 senitivity) will show up accurately (regardless of pos or neg) with random thru-the-day pee? Thanks!!!

I didn't test with first morning urine and got a positive at 5 weeks

Usually you just need to hold it at least 5hrs before testing. Don't drink a lot either in that time because that will dilute it and can give you a false negative if you are.

I got my BFP around 7pm and I drank water and pop all day had no idea I was pregnant just felt funny lol I couldnt believe it so I drank a ton of water and tested again around 9pm lol and still got a positive!! That was 3days before my expected period!
