Possibly not ovulating

[Namechange51]

I’m charting on Kindara and using a wink thermometer. I’ve been doing it for a few cycles and my cycle seems predictable and pretty much following the expected pattern. This was my first month using ovulation tests though and now I’m worried I didn’t ovulate. I have done 2 ovulation tests per day for the day before, of and after my predicted ovulation and none have showed an LH surge. Does this mean I didn’t ovulate? The temperature drop make it look like I have ovulated though. I am so confused and a bit worried. I am not ttc this cycle but I have now started to worry that there might be something wrong. I have attached a screenshot of my chart. Can anyone help me understand what it means?

It looks like maybe you ovulated cd 12. Really, you won't be able to tell until the end of the cycle (or closer to the end. Some women just don't get on with opks, despite ovulating.

I used opk this cycle between days 9-18 and I didn’t pick up any fertile days at all. I’m now a week late for my period so either I ovulated later than day 18 or I didn’t ovulate at all either ? In that case I don’t know what happens! I hope you figure it out soon xx
