Please don’t freak me out!

I’m 6 weeks 2 days today! The past 2 weeks Iv had extremely bad nausea and on Monday was vomiting in the morning! The nausea stays all day long and Iv gone off food especially when I can smell it cooking! However last night I made a Shepard’s pie and was okay with the smell, still felt sick but it wasn’t as bad! Today I don’t feel sick at all! I’m so worried the baby has just stopped growing and that’s why I don’t feel sick anymore 😭 please if you had this and then had a miscarriage please don’t comment as I don’t think I can deal with the heartbreak before work tomorrow! However if you had this and the baby was fine please please let me know and I could do with some reassurance!
