Opks vs fertility monitors????

My cycles are generally very regular, every 28-31 days. I also always get positive opks at cd 14-16 depending on if my cycle is closer to 28 or 31 days that month. With that being said, I am just wondering if it’s worth investing into some kind of fertility monitor that actually tracks my hormones rather than just looking at a test strip for that LH surge. I’ve looked into the inito monitor that shows your different hormone levels, 6 fertile days, and confirms ovulation.

I guess I’m just worried that I’m missing something and maybe I’m ovulating later than I realize, or possibly not at all.

My husband is gone for work a lot, and we often miss a lot of days throughout the month. So if my timing for ovulation is off (which is when we make it a point to make sure he’s home), then there could have been plenty of months we’ve missed our opportunity and maybe that’s why it hasn’t happened yet?

For additional context, I won’t get into the details why, but my husband and I both had basic fertility tests before our TTC journey and doctors confirmed everything seems to be just fine. So any advice or help on if a fertility monitor, specifically Inito, is worth the money. Thanks everyone!
