Preggy Symptom?

Can you be preggy if you feel nausea (no vomitting) , small amount of pee and start growing a pot belly (lower abdomen)? I can't seem to breathe in and make it flat like before 😂 Are they symptoms of early pregnancy? However, I had my period for 6 days on 11 April to 16th but it came like 2 weeks later than expected. So what's happening? Not trying to be preggy so I have condom sex. No sex after my period. It had to be my period as it was heavy bright red.
