How do you guys tell if you are ovulating? I'm new to this so I'm so confused haha

Britney • I'm a happily married to the love of my life and I'm a 27 year old who is graduating university soon this year and is hoping to start having some beautiful babies soon! We have had one pregnancy and miscarriage at 7 weeks so far hoping for a rainbow baby
I trusted the clue app and I'm pretty sure it was a week off for my fertile window and I don't want to miss it by accident! I bought some ovulation tests but what apps or what do you guys do to know when to do the baby dance to get pregnant? Lol thanks!
