Wish I could figure out my cycle

Kayla • 27 year old social worker who can`t wait to have a family of her own!
So my period is now 4 days late, which with my irregular cycles isn't the uncommon. 
I took a digital test on the day of my missed period and it was a no, like I suspected cause my partner and I didn't BD as much as we normally do, and only a couple times around ovulation. 
But now it's still not showing up, no sign of anything....and after a year of TTC some days I really wish I could figure my cycle out. But it sure loves to throw me curveballs! 🙄
