Ovulating or not...that is the question

Carrie
I finally broke down and bought a 30 day ovulation test kit. I've done it before but wasn't accurate at all. According to this app my most fertile day was this pass sat 12 sept. Super excited that morning bc the test showed the same...so I thought (my temp was even higher that day than any other day). However 13 and 14 sep I was thinking I wasn't as fertile due to the test. Now this morning the lines seem more bold than 12 sept. Actually it looks as if the lines are getting more define as the days progress since the 12th. I'm so confused and have no idea if I was ovulating more 12 sept or if that was just showing me the start of a fertile time and today is no kidding now the day.  Pls see pictures and help me de stress myself lol and understand UGH
