Pregnancy I think wbu?

I'm a girl in my bf account so I have unprotected sex and for the last 3 weeks I feel nausea , fatigue , moody , emotional, dizzy, I feel congested, and I feel gassy like I feel like I have gas cramps. And 2 weeks ago I had very very light bleeding for a week but i kno it was not my period . I'm now 5 days late . Do I sound pregnant ???
