Thanks for posting your query.
Spotting could be one of the symptom of pregnancy
But it is not confirmatory evidence for pregnancy.
Ovulation test only suggests that you are capable of being pregnant.
Check for other symptoms like nausea
, Breast tenderness, fatigue
Now you can again check for urine sample.
If the sample is positive, you can consult a gynecologist for confirmation.
Hope I have answered your query.
Wishing you good health.
