No Symptoms

Just wondering how many Mumma's have had no symptoms during pregnancy? I'm 9 weeks and 4 days and other than the slightest nausea earlier on and being tired ( but I'm always tired) I have absolutely no symptoms... We saw a strong heartbeat at 7 weeks but I'm quite anxious about not having symptoms. I had 2 missed miscarriages prior to my daughter... Is it possible to have a healthy pregnancy with no symptoms? Thanks Mumma's
