Pregnancy symptoms?

Felicia

7 weeks and 2 days today. A little nervous and anxious because I don’t really have my morning sickness like I did with my first and second pregnancy. It worries me because by week 8 of my M/c, I didn’t have any symptoms. This pregnancy, I’ve been fatigued a lot and had some nausea but it’s not really there. I saw the heartbeat last week but still nervous that something may be off? Anyone experience not really having any symptoms even though they did prior?
