Totally not trying to scare you, but around that exact same time in my last pregnancy I started losing some of my symptoms. I never had morning sickness with either of my pregnancies though, just tender breasts and heartburn. Anyways, I kinda just felt like something wasn't quite right so I asked to see my dac s little sooner than I had originally scyth for my first prenatal check. He did an ultrasound for me a couple of weeks later (around 10 weeks I think) and there was a bag of waters with no baby inside. Turns out, I had 2 fetal sacs inside (twins) but nothing else. I ended up miscarrying about a week later. So my point is asking to see ur doc early wouldn't hurt and it will put ur mind at ease. Hoping best wishes for u and ur family!
Every pregnancy is different. I don't think you're having a miscarriage.
I think you would show other signs of miscarriage outside of not having morning sickness anymore. . some people have morning sickness on one pregnancy and nothing on their second pregnancy at all. . don't panic... when is your first ultrasound? Congrats and all the best! Keep me posted!
