Pretty crampy but no AF


I’ve been cramping past couple of days and my boobs are slightly sore. Flo said I should’ve started Monday, Glow says today. I did test negative this am. Normally once my cramps start I’ll have a little spotting but no sign of it. How many people had tugging or burning like cramps right before their Positive test? Need some encouragement cause I’m getting impatient! Thanks!
