5 weeks 4 days?

Thalia

I’ve taken 2 test and they’ve both been negative. I’m still a bit confused as to why my period is now 11 days late, (it usually is not late). I’ll be taking another test on week 6 (in 4 days). I did start a new job a bit stressful could that be be reason for my mossed period? I have small symptoms but not many.. increase of smell, some nausea, extreme back pain.. what do you guys think? 😓😓
