Advice needed!! Weird changes

So... I'm on week 8, and weird changes happened like from evening when I went to bed until morning when I woke up 😬 I woke up 3 days ago and didn't feel so tired and nauseous anymore, and also don't have so much cramping. Now I feel more energized, I can eat something, and it feels unusual, since I've felt very bad for last few weeks😅 I haven't had any spotting 🙏 is this normal? Or should I be worried and go to doctor before my appointment on 2nd of january? Please help! 🙏💖
