Would it be obvious to you that you're pregnant at 9 weeks? meaning would you feel pregnant.

Usually. Not always.: A woman of childbearing age who has some nausea (with or without vomiting), some fatigue (feels less energetic), a sharper or stronger sense of smell, mild soreness or swelling of her breasts, and maybe some food aversions and cravings... could be pregnant. Symptoms can occur before missing a period. Early symptoms start around 4 weeks of pregnancy. Some women are more perceptive than other women.
