Miscarriage 4 weeks ago- ovulating?

I had a miscarriage and started bleeding 4 weeks ago and the mc was officially confirmed June 1 when my levels were dropping. I had bleeding and then it stopped then on June 16 I had what I think was my period. I have taken ovulation tests and seems positive- is this a true ovulation or is it capturing my levels? The test was darker yesterday than today. The top pic is today bottom was yesterday. Help!!
