No peak/LH surge?

2nd month TTC. I tracked my ovulation with the iProven strips from Amazon last month and never got a 100% clear positive. I was only testing once a day then. This month, I’m trying to test twice a day, but I haven’t gotten my positive yet, even though I feel like I should have by now (my cycle is a very regular 27 day cycle). I’ve gotten a few almost-positives (11/3 evening, 11/4 morning, and again 11/5 afternoon), but it’s only part of the line that’s darker than the control line. Thoughts? Did I ovulate after all? Or not yet?
