Freaking out

So I’ve used this app for about four months. Used to use it before having my baby. Anywho, freaking out cuz my period hasn’t been on time AT ALL since starting to track. I just noticed that since my period didn’t start (again) today (it’s like three days off from my last period, but they haven’t been consistent at all on the app) that my ovulation ALSO changed in the past. Making New Year’s Day my highest for ovulation. Well before it said 3% chance of pregnancy and drunk me and my man had tons of unprotected sex. There’s probably not a ton to say here but does anyone have insight?! I’m freaking out. I dont even know what I’m asking.
