9.1-FTM-symptoms subsiding?

Hi guys! Yesterday my nausea came in waves but I was able to eat a CHEESEBURGER my first real mean in a while so I was super excited! But today so far there hasn’t been much nausea at all so I’m excited that maybe this is the light at the end of the tunnel but also nervous they may be going away too soon??? I heard a Heartbeat of 162 at 7.6 weeks so I felt good about that. I just never know! I’m an anxious person by nature and I just want to be out of the first trimester so I can relax just a little!! Any advice?
