Disappearing symptoms

I’m exactly at 7 weeks. I’m 34 and this is my first time pregnant. I had some fatigue, intense hunger, slightly sore breasts that have grown some, light on and off cramping/stretching, thirsty, and frequently needing to go #2. NOTHING else. No other symptoms at all. I barely feel pregnant. Maybe a little bloated too?

ALL of that has disappeared! No spotting. No pain. Breasts are still bigger and shirts and bras are tight. No frequent urination. Normal bathroom habits as before. Normal appetite. No more extra thirst. No crazy appetite. Pulling and achy feeling now gone. Nothing at all. Should I be worried? 1 weeks of NO symptoms. I feel like I did before pregnancy. Just tight clothes. Help?
