Opk help

Nicola • Married. 29 years old. Mmc at 11 weeks July 2015 and mc at 4+3 weeks Nov 2015. Pregnant with baby girl due 30.07.17 ♡♡
I took this opk and it looks pretty much positive but the dye run hasn't settled even after 30 minutes! I took another about 30 mins later and it's negative. Did I get my positive opk or not?
