digital ovulation test?

When should I start testing? I started af today.

if you don't' know when you o I would test from the day it ends until you get a positive. Most ( not all) Ovulate around 2 weeks after the first day of their period ( day 14) but not everyone is a text book 28 day cycle o'ing on day 14. I always ovulated on 18-19 and had a 28-33 day cycle. once I ovulated on day 11.

Ok Thank you! I have no clue when I o. I used to have a normal 28 day cycle and since mirena/depo my periods has been all over the place I'm not even sure if I'm o'ing at all.
