TTC WITH IRREGULAR PERIOD

I’ve been ttc for over 3 months. I am 26 and have irregular periods. I purchased some ovulation strip kit on amazon and I have two apps that should be try to find my ovulation date. Yet I always have such a hard time figuring out when I ovulate. My cycle is 26 days on average one app says I ovulate right after my period. The other says about 7-12 days later. I just finished my cycle and here is what my strip says. What do you guys think? is this neg or positive? Also any tips for us ladies with irregular periods :(
