Is this a positive ovulation test?

I had a miscarriage 15 days ago, for the last 3 days I've had a headache, this morning I felt nauseas and had some cramping like my period is coming.I normally don't ovulate on my own and when I got pregnant I was on clomid and I remember feeling the same way. Yesterday I took an ovulation test and I thought it was negative and I checked it again an hour and a half later ( I was at work) it was positive. I just took another one and I took a picture of it (2 pics actually).  my bf and I have been having sex just about everyday since the miscarriage. Does it look positive to you? Should I take another one tomorrow?
