anxious and not feeling pregnant

Kassandra
9 weeks 5 days according to glow. I don't feel pregnant other than being tired. I have these anxious thoughts that I'm not pregnant or have had a miscarriage even though I haven't bleed or anything. Waiting on my first ob appointment on 5/31. I tried a Doppler to find the heartbeat yesterday and couldn't hear one. Anyone else have these feelings or thoughts?
