Late period question

My period is late (some apps say 10 days some say 5days and it was suppose to come yesterday according to this app) but my period has been irregular so idk if it’s late or not (for two months i had my period twice, and the second time was around this week) anyways i been taking pregnancy test (Bc I’m sexually active and been using condoms but my precious period is late 🙄) anyways lol I’m stupid Bc i didn’t know you should take the test during the morning and not night time. So i guess what I’m asking is... are the test not accurate ? (They said negative but i took two in the afternoon and evening) pls help
