Hello all! My period has been very VERY regular for the past year.

I have been trying to conceive so part of me is thinking I’m just looking for signs I might be pregnant, however, I’m 3 days late for my period and I didn’t have any of the usual signs of my period starting. Normally the week prior to my period starting, I have sore, swollen breasts, cramps and fatigue.

I had none of these symptoms, I’m 3 days late and the only thing I’ve felt is fatigue. How late for my period should I be before taking a pregnancy test?
