Pregnant and no symptoms

Nancy • Pregnant with baby #1. I am 25 recently moved to the US
Hi girls I am 5 weeks now. I just know I am pregnant for the bfp last week but I don't have the morning sikness, smell, nothing. I am wondering if anyone else didn't have symptoms at all and if it should be something to worry about. I have lost 0.7 pounds in the last week and I feel that I have been eating more even taking prenatal vitamins.
