I'm getting too worked up 😰

My period is 10 days late ... Ive done a few tests but only a few cheap ones, they keep coming back the same! Ive been noticing nausea , headaches , achey/ crampy stomache, sore nipples and boobs ! My armpits are sore As well. But I think the most thing that I noticed was my nipples feeling on fire when they got cold !  Can someone please give me some guidance ? I'm 22 and never really had any mother figure
