Any pregnant mamas feel like this?

According to Glow, I'm 6 weeks pregnant. my first appointment isnt until the 15th and my first ultrasound iant until the 20th. I was having major nausea in my 4th and 5th weeks and slight breast tenderness. now I just dont feel anything. I just have the biggest feeling I'm going to get to the appointment and there will be no baby. home tests still keep coming out pregnant. I'm sure symptoms come and go but this is my first baby so I just really dont know. I've had no bleeding or spotting and no intense cramping. is this all normal or can someone just try to make me feel a little calmer? please and thank you 😭
