Nausea sickness dizziness for 8 days

Chelcie • 28. Mum to 2 girls 🫶🏼 UK

8 days STRAIGHT. Everyday, today at work I’ve been sick. I’m working 12.5 hours at the hospital, it’s so short staffed I need to go home but doubt they’ll let me

Period isn’t due for 6 days ...

is it really too early to test? I think it is but that’s all everyone tells me

... what Can I do / what could it be ?
