Symptoms and nervous,

I am 6 weeks and 2 days today. I haven't had really morning sickeness, just nausea everyonce in a while. ALWAYS tired and exhausted. Tummy is getting a little bigger. I have my appointment on the 26th at 8 weeks and 4 days. I am so nervous there won't be anything. Since I had a miscarriage at 5 weeks. Ugh.. :/ my question is has anyone else not feel sick but there baby was perfectly healthy at ultrasound?
