Help!

So today, I went for pelvic ultrasound. My Doctor called me back to tell me the result. They told me that i still have pcos and they saw a fluid in my uterus-- she told me possibly an early pregnancy (i really pray i am pregnant 🙏🏼).. so they advised me to take another pregnancy test. It just confused me coz i have my period right now (which arrived a week early).. what are your thoughts? Tia ❤️!
