when to test.. any negatives before positive?

my period was due the 19, yesterday.. i missed it clearly lol. my period app is very accurate with when my periods are supposed to come.. i cramped but nothing, i never had sore/sensitive nipples but today, they were the first thing i noticed.. i tried having sex to get my period to come (it’s worked before unintentionally) but nothing 😕 i tested & got a negative .. i feel normal af other than me sleeping a lot .. when should i test again ?? have any of you got negatives and then positives ? it’s like i know i am , but i don’t because of the negative test

P.S. i had unprotected sex the day after my predicted ovulation day & he shot the club up 💀💀💀💀
