In need of help (OPK)

Zoe
Hello guys! I am new to TTC I'm on baby #1 however have been pregnant before but miscarried with ex partner! I have taken some opk's to help track ovulation! 
​In the picture the first ovulation test was CD13, then CD14 and jumped to CD16.
​I think the last one is positive but please tell me if it isn't ;) 
​All comments are appreciated
