Symptoms Easing Up Around 9 weeks?

Looking for some reassurance! Saw healthy heartbeat at 6.5 weeks- now 8w6d, have another ultrasound tomorrow. Weeks 6-8ish were definitely the worst for me - insane fatigue, gagging, lack of motivation, food aversions, etc. The last two days I've been feeling... better? Not 100% but better than I've felt. I've read that some women feel like death until end of 1st tri, whereas others start to feel better around the 9 week mark as that's when the placenta starts to take over. Is that true? Let me know if you feel similar!
