Hi October babies!

Question! I had pretty severe exhaustion and nausea for a solid week (about week 5.3-6.3), and it’s subsided substantially. I don’t feel 100% and the aversions are still there, but I thought the nausea was supposed to increase in severity after week 6. I was so sick I was on the verge of prematurely telling people as to explain why I was so out of it, and now I’m sitting at work totally fine. Not complaining, but is this decrease in symptoms a cause for concern? Is anyone else experiencing this shift?
