5 days before period due

I don’t symptom watch and I haven’t been that serious about falling pregnant (SO and I decided in October that we wanted one more). If it happens it happens. I don’t track my ovulation, we BD a few times more then usual during ovulation week that’s about it. The last few days I have noticed a tightness in my stomach, I have sore heavy boobs, stomach cramps and food isn’t fazing me. This close to my period I’m usually a mental case, chocolate crazed lunatic. Would it be too early to test? How many of you have gotten a feint line this soon before AF was due?
