How long should i wait ❤️

Hey ! So I’m 9 days late and i took a pregnancy test 2 days ago and it said i was negative... i have been cramping for a few days now along with some heart burns. Today i tried the “salt pregnancy test” and it came out positive 🤔 my <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a> just keeps pushing my period out 2 days 🤦🏽‍♀️ how long should i wait to take my next pregnancy test (opinions welcomed) 😁
