Symptoms lessening...should I be worried?

So I’ve been struggling with pretty bad all day sickness since around 5 weeks, I’m 9 weeks 3 days now. Just this last day it’s gotten better, I also have had no usual cravings. Breasts are still a little sensitive but other than that I feel pretty normal. Should I be concerned? I expected to start feeling better toward the 2nd trimester but thought it would take longer. Have had two great ultrasounds, strong heartbeats on both. Never thought I’d miss the nausea!!!
