Pregnancy symptoms feel like they went away

Cr

I’m 40, 10w 5d pregnant with my first and I had a few pregnancy symptoms the first few weeks. Mild nausea, fatigue, sore breasts, constipation. I had an appointment at 7 weeks and we heard the little bean’s heartbeat, all looked good. About a week ago the few symptoms I had seemed to go away. I’m getting my energy back, (still a little tired) and a little constipated, but other than that- I don’t “feel” pregnant. A little thicker in the midsection thanks to the 5 weeks of a sweet tooth I had.... But, No discharge, cramping or other symptoms. Has anyone else experienced this? Am I just feeling super paranoid? Should I just be considering myself lucky?
