Not ovulating/strange cycle

Cat • I have the life I`ve always dreamed of living.
So my partner and I have been trying since the spring to get pregnant with no luck. My cycle decided to get a little crazy this summer and after men's treating the first week of July I didn't menstruated again until the first week in September. I decided to get the clear blue fertility strips to really track my ovulation patterns but I'm on cycle day 23 and no LH surge :( 
​Could this be bc of the weird cycle I just had or should I be concerned?
