1st Time Ever Tracking Ovulation

Okay so I decided to go and track my ovulation and see if I’m actually ovulating. I never tracked before because it has never been difficult to become pregnant for me. I have 2 kids 9 and 5 boy and girl and I want another baby. 🥺 I ran to the store this evening because I wanted actually see if these apps I’ve been tracking my period on are even close to being correct. Right now currently I’m on CD 12 My cycle length is 27 days. Last month my period was 4 days late AF she showed up CD 30. According to these apps states today should be my “peak” I should be fertile does these results indicate I am ovulating or not ? Or barely ??? I’m so confused please HELPPPP!
