When should I start being concerned?

So today is supposed to be the second day of my period according to glow but since January my period shows up 2-3 days ahead of schedule every month. When AF didn't show up early I was happy like ok finally getting back on track but now it's late and it's never been late before early sure, never late though and I the dumb ass that I am had sex 2 during my fertile week according to glow withdrawal was used once and unfortunately wasn't used the second time 🤦 he wasn't aware I was in my fertile week and I didn't think to tell him because he always pulls out without fail. I'm aware I should be taking better precautions against getting pregnant. I'm actually waiting on my bc in the mail it's taking longer to be delivered than I expected. Regardless I'm just wondering when I should be worried because I'm not having any of my usual period symptoms either no aching hips, breasts, no cramping or bloating either. Any advice is appreciated.

EDIT: I'd also like to add the increased appetite, frequent urination, exhausted no matter how long I sleep, and takes hours for me to fall asleep haven't been able to get comfortable lately.
