Ovulation kit result. Happening at all?

Hello doctor, I am using an ovulation kit these days to track my fertile days and my last period date was 16-Aug-22. I started using ovulation kit on 9th day , 11th day, 13th day, and 14th day , 15th day and ever time I got one dark and one faint line . Now I am confused that in this whole time period did my ovulation occur not and how long should I continue to track . Also the line is faint but there is some pinkish color in the two small lines which is at the end of the strip . Attaching pic for reference. Does this mean that my ovulation is not happening at all? History : I lost my pregnancy due to incompetent cervix in March 2022 at completion of my 4th month . Please advise how can I track my ovulation and what can be done if it is not coming up through this kit .
