Should I take a test!?

Hi ladies, so for the past week I have been feeling very neausous I don't vomit but the feeling is there today I was suppose to get my period but I haven't normally 3-4 days before my period is due I'll start getting aches down my thighs and light cramps and they get worse until I get my period but still no aches or cramps should I take a test or wait it out?
