Chemical last cycle and now not ovulating

Well I guess I haven’t ovulated yet this cycle. I’ve been ovulating around Cycle Day 18 or 19. I had one high temp on cycle day 21 so I thought that was my trend of high temps to confirm ovulation but nope, it looks like it was just a one time high. I use opk too and I got a positive on cycle day 18. I took one yesterday just to see and it was very close to being positive. Maybe my body has been trying to ovulate and not successful?? Anyone else have a problem ovulating after chemical pregnancy?
