Paranoid

I'm just shy of 5 weeks. I found out on what should have been period day that we are pregnant. My first pregnancy ended in a miscarriage at this point. My second, thankfully, resulted in a beautiful, healthy little girl. With my daughter I had quite a few symptoms, nausea, very tender breasts to the point I couldn't shower comfortably, crazy bloating where I switched to pregnancy pants almost immediately for comfort, etc. This time around I'm barely feeling anything and it has me terrified. I know each pregnancy is different but this is a bit drastic. Anyone able to provide some comforting insight/experience? Thank you!
