7+6 weeks no symptoms

According to the app, 7+6 weeks. HCG last week was 13,800 (don’t remember the exact number). I miscarried in Dec 2016, so I’m on edge about everything. My first prenatal and ultrasound isn’t until the 22nd. I have no symptoms of being pregnant, other that peeing a lot, but I’m also drinking 2 liters of water a day. Some bloating, not much cramping or back aches. On a scale 1-10 breast soreness is only about a 1-2. No nausea or morning sickness (no symptoms with my daughter 5 years ago either). Should I try to move my appointment up? It’s so hard for me to get out of work since my boss doesn’t know. Just don’t want to loose my baby, and freaked about the no symptoms thing. My miscarriage I was 10 weeks, but baby was only measuring for 8+5 weeks. So almost 3 weeks inside me with no symptoms I was misscarrying.

Advice please?
