How long of a hold do you do??

Still getting flashing smileys- day 6! Was reading most people get positives in the evening, and have been testing 2x a day since first flashing smiley.

My question is how long of a urine hold do you do before you got your static smiley? I can’t keep trying to hold it for 4 hours every night before bed, and I don’t want to if others haven’t had to do it!!

Advice appreciated!!!!
