I have a delay in my period and I feel nausea and my body is feeling sick 🤢!!

So my last period came June 30 and and ended July 3 .. after two weeks I started to feel sick like with a lot of nausea so I took a test to check if I was pregnant, and it was negative 👎🏼.. it's august 10 and my period is still not here and I feel 10 times worst, boobs hurt like hell and I have nausea, sometimes I even feel like drunk hahah like super dizzy, my body defences are super low I know cuz I got the flu (i usually don't get sick at all) so you guys think I have a hormone imbalance or maybe All this is because am pregnant?

Thanks girls !!!
