AF supposedly due in 5 days!

saggy

I want to test sooooooo bad especially since my period hasn’t come the exact day Glow says it will. Right now I’m having mild cramps and I’m very gassy. My breasts have been so sore for 3 days and are only getting worse 😣 I hope these are signs? Would you test with an early detection or wait? It’s killing me! Please comment thoughts 💓
