Could I be Preggo???

So I'm 2 days late on my period, my last period was on August 6th, and my periods always last about 5 days each month. I'm 21 but I'm still learning to keep track of my body. I know about CM and a little about ovulation....me and my Bf constantly have unprotected sex (yes he comes inside) but I'd really like to know from someone whose experienced pregnancy before if I could possibly be preggo. I know it's still to early to test so this is QTNA lol! ???? I really just feel a tad bloated, gassy, and tired as far as symptoms. Please help my bf & I are so excited and anxious he's more happy than I am so any positive feedback helps thanks
