Late period

Hello you guys I’m new on here so take it easy on me 😭‼️, I have been trying but not trying to get pregnant, I kinda just want to happen for it’s self because you know how it is to get discouraged really quick when things don’t go our way , anywho I’m like two days late right , but we all know how periods can be I am regularly and it normally does start when my app says so I’m wondering should I wait til the 19 since that’ll be like the 4 day IF it still doesn’t come on or ?, help and baby dust 🤞🏽🥺🥹👎💜
