Help, is this a positive OPK?

Katie • Trying for our first baby. 31 year old
Hello! Since we started to ttc this winter my cycles have been all wacky.  One month my cycle was 42 days and the next it was 30 days, making it very hard to predict ovulation.
​ My test today was the closest I've seen to a positive ovulation, can someone help confirm if they think this is positive or is the line too faint?
