I need help with my cycle length!

Jj

Hey! So I was on pill birth control 10 months ago, I quit taking it due to we wanted to try for a baby, well we have yet to succeed, my cycles vary each month it seems like, my last period I had a normal 28 day cycle I was actually happy about lol and now this month I’m on cycle day 30 and haven’t got my period yet, but according to glow it should be here tomorrow.

Anyways, how can I figure out what my cycle length should be by adding and dividing my cycle length number and dividing by months? I know how to do it just can’t seem to get an actual answer.

Also, would you consider my period to be late right now? I haven’t talked lately cause it seems like every time I talk about my period possibly being late it shows up. I hate it lol

Looking for advice on really anything, if you have periods like me, or just wanna talk I’m here! Thank you!
