Does it mean a miscarriage is coming if....

You don’t feel fatigued anymore?? I’m almost 10 weeks and for the last couple weeks I’ve barely been able to get myself off the couch. Today, I actually feel.... good? 😳 I had a ultrasound a week ago and we saw the heartbeat and baby moving around but, could me suddenly feeling energetic mean I’m going to miscarry?? Or am I just worrying for no reason?
