Period is late

I’m 21(f) and I am having protective sex with my boyfriend 22(m) , I came off the pill after being on it for 5 years , I was still using a condom while being on the pill as I have a fear of getting pregnant. I am currently 5 days late for my period and felt a little nauseous this morning. I had cramping this morning but still haven’t gotten my period, my bf is freaking out but I feel like that’s stressing me out and delaying my period as I know stress has an effect on your cycle. I have also moved house this month and I think it had an effect on it too . Any thoughts would be appreciated.
