Whyyyyyy???😭😭😭😭

I swear ever since we started ttc my period has been so messed up😭 For 13 years it always showed exactly every 28 days like down to the HOUR. Last month it was 10 days late and now it’s 5 days late (even though the app says 4). I don’t even want to test because I know what it’s gonna say anyway. Has anyone else has this happen?? We’ve been ttc for about a year now, I’m 25 and he’s 28
