Are there any symptoms when you are less than one month pregnant?

Patient's question:

Is there any symptom when you are less than one month pregnant? Can someone tell me, thank you

Doctor's answer:

Hello! Amenorrhea is the earliest sign of pregnancy. If your period is a week late, you should suspect pregnancy and go to the hospital for a urine HCG test to confirm. Common early pregnancy symptoms include picky eating, nausea, vomiting, salivation, frequent urination, fatigue, and drowsiness. Generally, pregnancy symptoms appear around week 6. Early pregnancy symptoms usually occur about 10 days after the missed period, which is roughly 40 days after the last menstrual period. The symptoms are mostly nausea and vomiting (more pronounced in the morning), chest tightness, breast tenderness, and high body temperature.
