If i dont make this cycle

If I don't get pregnant this cycle I think I'm going to try a different opk this was my first time using them and honestly the strips I used weren't accurate they we're saying I wasn't ovulating even on the day I ovulated if it was for glow and me checking my cm I wouldn't have caught I've been testing since cycle day 9 I am very familiar with the signs of ovulation so even when I saw the clear cm and got the other signs the strips we're giving me negatives I was trying to save money by ordering off amazon next cycle I think I'll go the more expensive way can you girls give me some names of good opks I used off brand I should have went with wondfo
