Am I crazy?

Kennedy • Married to my soulmate since 7.4.2020!💍💞 We have a 4 year old son, who took a year and a half to conceive! We are expecting baby girl March 11th 2021 after 2 1/2 years of ttc with fertility treatments 💖
Its it impossible to have pregnancy symptoms 4dpo? I feel very nauseous and I have slight cramping. Or is it my mind playing tricks on me?
