Can you have pregnancy symptoms 2 weeks after period an be pregnant?

I've been feeling slight twinges in my breast an the last 3 days my stomach has been upset like feeling nauseated felt dizzy out of no where yesterday had a sore thoart for a day or so an a snuffy runny nose for the last two days

Can you have pregnancy symptoms this early? I'm not due for AF till the last week of October

Just wanna see if there's anyone out there in the same boat or has had this happen this early?
