Sometimes it isn't easy, but you need to try and relax. My pregnancies never seemed real until I could feel the baby moving. I just felt sick. It's not a bad thing to feel pretty normal, it means things are going well.
If this is your first pregnancy, it is normal to not show until well into 2nd Tri. Everybody is different and one person having or not having the symptoms you are experiencing has no basis on your pregnancy. GL!
ETA: I had bleeding around 5 weeks with my DS that was considered a "threatend miscarriage", but the bleeding stopped and I had a very uneventful 9 months and a very healthy son.
