Advice?

So I haven't gotten a positive opk this cycle at all. I started testing for it on CD 13. BUT I had really bad left pelvic pain on CD 9. Today is CD 19. My period was march 31st-April 3rd. Does it sound to you like I may have ovulated earlier than when i started testing? I'm really hoping because i never ovulate late and I'm thinking of I didn't ovulate early then I may not have at all? I guess this post is more about asking for hope lol I know there's no way anybody could know the answer.
