Ovulation on cycle day 17

Hi, quick question... Last month on January was the first month that I've been using the opk test strips. I got the pregnate ones, so basically I saw a post here where someone said something about not have a successful pregnancy due to ovulating later than cycle day 14. Is that true, because last month I ovulated on cycle day 17 and I did everything possible to get pregnant and I AF showed up at 11 DPO!!! My husband and I have been ttc for about five months already after I took out my Cooper IUD back in September and still no luck. AF is about to to end already so I'm going to try again the opk test strips to see that hopefully I do end up pregnant, but if I'm ovulating later and it's a problem then I think that there's no point of me trying to get pregnant 😔
