Could I still Ovulate Please Help

So I would normally get a positive opk by around CD10 bur as of yet there all negative the line is there but not as dark as the control line 😰

Is it possible that I could still ovulate I was hoping after my temp rise yesterday that would be it and it would stay up but it has dropped again this morning. This is my first proper month using bbt. Tried it last month but I kept missing days here and there to take temperature. Any advice much appreciated

Thanks
