No symptoms

Hi mummies, this is my first pregnancy. My first day of last period is 26/7, I went for an ultrasound on 31/8 and the dr said the baby should be 2 or 3 weeks and it's at the perfect spot. At that time I had cramps, swollen breasts, and a few other symptoms. Now I'm not having any symptoms except for bloating and only sometimes I feel tired if I work. Is this normal? The dr gave me an appointment on 21/9 but till then I'm quite worried if the baby is alright or what. Coz I googled about this and it stated there will be symptoms during this time. Since it's my first pregnancy I'm kind of confused. Kindly advice mummies!!!
