Not feeling pregnant.

I am 6 weeks today and I have very slight symptoms like bloating and a bit of stretching in the abdomen area but other than that nothing. Also my first appointment is not until April 8th! When I was 4 weeks they did test my HCG levels and they tripled so that was reassuring. I am worried because last time I miscarried at 9 weeks and I also had very little symptoms. Is anyone experiencing the same? Or have had no first trimester symptoms and gone on to deliver a healthy baby?
