I wouldn't say lockdowns changed my lifestyle that much apart from not being able to see my boyfriend as we still live with our parents and that's been stressing me quite a bit not seeing him, but I'm wondering if anyone's noticed the same with their menstrual cycle as well. Before lockdown started in 2020 my period would start almost on the day this app predicts but now its all over the place, I was supposed to have started 3 or 4 days ago and it hasn't.
