Symptoms disappeared

Hi everyone, I just needed some advise / reassurance as I'm freaking out alittle .. I'm 8.4 weeks pregnant, haven't had any scans yet. I had awful morning sickness for the last few weeks.. nausea from the minute I wake up to when I go to sleep.. vomiting several times a day and being exhausted.. but I've woken up this morning feeling like I normally do.. no sickness, no nausea and but tired.. and even tho it feels great to finally eat and get stuff done but I also feel really worried something is wrong. With my first pregnancy I had morning sickness till around 17weeks preg.. Has this happened to someone else and every thing has been ok ? Can't help but worry :(
