So I was meant to get my period 3 days ago and it normally goes for 3 days and I still haven't gotten it

Should I be worried or should I be happy ??

I've got tests of I don't get my period within the next week but I'm a little bit scared as I've just gotten a new job and if I'm pregnant I don't know how the boss will take the news and worried that he might fire me considering I'm on a casual basic

If I am pregnant it's definitely not a planned one but if I am I'd be keeping the bubs anyways cause I had a miscarriage with my first bub a couple of years ago with my ex partner ......
