Not sure

So my cycles used to be 28/29 days and then I had my daughter in 2020. She’ll be 3 October. Since then they’ve been anywhere from 25-30 but averaging 29 days according to my app. Today is day 31. I’ve never gone over 30. My husband keeps asking me the past two days if I’ve gotten it. I think he’s excited because we started trying again/not preventing last October when she turned 2. I don’t want to get his hopes up and I’m also a little nervous/scared because her birth was very traumatic but the pregnancy was great.
