What day should I test?

I know I always end up coming in here and getting my hopes up nearly ever month. I’m pretty sure I have been ovulating 3-5 days early. I can’t use OPKs because I end up over thinking it and they just don’t work for me and my husband. I am 9dpo from the apps prediction, about 10-12dpo from when I think I ovulated. I tried to take a test earlier today but it was negative. I’m wondering if it was negative because it wasn’t first thing in the morning and probably pretty diluted since I’ve almost tripled my water intake the past 2 months. I do take progesterone for the first 10 day of my cycle then letrozle CD3-7. I’m not really sure what else I can do to track ovulation that won’t add the extra stress of tracking. Anyways should I retest in the am? Or just wait to see if my cycle restarts in the next 5 days?
