Symptoms suddenly gone?

Destiny
Hey everyone! I'm 8 weeks today. I have been insanely tired since about 5 weeks, and I didn't really have any other symptoms until about 7 weeks (nausea, headaches, etc.). The last two days, my symptoms have been gone. I have more energy and my nausea is gone. Should I be concerned? Should I contact my doctor? Is this normal? I know I'm super paranoid (this is my first pregnancy after trying for over a year, so I am very nervous and over analyze everything!). I had an Ultrasound at 6w4d everything looked good, and my next one is next week (on Wednesday). Any advice is appreciated! Thank you!!
