Am I over reacting?

Feeling like I'm not showing when I thought I was starting to. I still have pregnancy symptoms but I lost 10pounds by the time I was 10weeks. I lve only gained 2pounds an I'm almost 15weeks. Is this at all normal or no? I've been having wait I thought were growing pains now I think it just may have been cramping. I just don't feel pregnant anymore I guess. Morning sickness is on an off an it's the only symptoms I have besides being sore I guess. Honestly I'm starting to just not get my hopes up... I can't even use my Doppler because I get disappointed every time I can't hear the heart beat. So I guess my last question... Can you miscarry but not bleed?
