Not feeling pregnant

I’m 13 weeks tomorrow and have no reason to think anything is wrong but I’m just looking for some reassurance. My bloat went down significantly and my symptoms are gone besides not sleeping through the night and fatigue. I don’t FEEL pregnant anymore. This has happened before and it came back but I’m over a week away from my next scan. We got healthy NIPT results, multiple healthy ultrasound scans and everything looked good. I have a Doppler but I’ve never been able to find the heartbeat so matter what I do.

Is there a chance something is wrong? Am I in my own head? Thanks all.
