Am I pregnant?

Hey girls my last period was late because of stress and came a week late, since that period I’ve had sex 5 times all protected (used a condom) but because of the late period my period app reset and is not saying that my period will come in 28 days when it usually always comes in 23. Today it’s day 25 without a period and I’m thinking that maybe me and my partner didint take enough precautions and that there is a risk im pregnant. Is it normal for my period to come at the same time of my old period or should I be concerned because the app is telling me that it will come in 3 days!!! We used a condom and he also pulled out.

Ps: I don’t know if this could also be a reason but it’s since last Monday that I’m in Italy
