Sudden Loss of Pregnancy Symptoms

I am 8 weeks. Weeks 6 and 7 was feeling really awful, Morning sickness 24/7, then a few days ago sudddenly all symptoms seem to have stopped. I have tons of energy, my appetite is back full force and I can eat whatever i want without feeling sick. Should I be worried about a silent miscarriage, or can someone else vouch for having gone through this and everything was fine? Thanks in advance for any feedback!
