Confused and waiting. Feedback requested!

A bit of history, followed by a question: I had a miscarriage last June, and we've been TTC again since Sep. My period is pretty regular most months but I do have longer cycles, anywhere between 30 and 34 days. In Jan and Feb I did get positive ovulation results, around day 18 or 20. This past month was a bit of an "off month" - both my husband and I were traveling at separate times, and I was sick with a cold for most of what should've been my fertile week...I wasn't super great about testing for ovulation and never did get a positive, but we did manage to try on days 16, 21, and 22. It is now day 36...absolutely NO signs of a period (usually I get "fake period" for a few days leading up to real period, with spotting and bloating), and my CM was super fertile-like for the past week or so. I've taken pregnancy tests the past few days and keep getting the BIG FAT NEGATIVE.
