My puppy is 7 months old now and she hasn't started her period. I pretty sure she hasn't been in heat too. But I'm worried she'll start unexpectedly

That is very difficult to predict to be honest. She could get her heat anytime in the next 5 months or so or she could have got it already.
Often the first heat has no signs at all or just few signs, that is why is difficult to say.
