40 day cycles after quitting the pill

I have been off the pill since March, actively TTC since June. My cycles have been just around 40 days long since I got off the pill and they don’t seem to be going back to normal. I read online that elongated cycles can be the result of anovulation aka not ovulating at all. I have taken a few home ovulation tests around the time that I guessed I might be ovulating and they were all negative. Does anyone have any experience with any of this??? I’m frustrated and discouraged. :(
