Period late

Period is late by one day extremely gassy, heartburn, constipation, feeling sick, fatigued, and just in general not feeling right I took a test about an hour ago and it was negative. I really want my positive and I just want to know if anyone has experienced this and has gotten there’s. Should I wait a couple of days and test with fmu or could I test in the morning? Please no negative comments. Thank you!!!❤️
