Late period, no symptoms

Hey guys

I usually get my period every 26-29 days, it usually last 2-3 days but there is bleeding not spotting but not heavy.

My partner & I started to ttc this month.

My period is now late, I’m currently day 31. I had cramping during the week, my boobs are slightly tender but not that bad but I’m aware of them.

No sign of my period.

Would you test?

I’d assume having no symptoms like fatigue or nausea means I’m more then likely not pregnant,

But where is my period?
