Not ovulating/late ovulation

Been ttc for 3 months - 1st month ovulated cd16, 2nd month ovulated cd18 and this month i am on cd25 and have had 9 days of high fertilty on clearblue digital. I assume i should give up on assuming i'll ovulate now this month. It's cd25 and nothing. I had my mirena out in dec so these are the only proper cycles i've had in years and all i have to go by. Anyone else experience similar? Please give me any advice or experience, i'd appreciate it
