Is this positive???

hey all i was wondering if you can help me figure out if this is a positive reading on my opk? i took a test this morning and it wasnt a positive (the test strip above the thick purple test) at all then i tried a different brand just now (the big fat purple one) and my SO and i think its positive. the side that has a "c" is the control side and the side that has a "t" is the test side. Thanks in advance for any input!!! hoping this is our month. first time using any predictor methods.
