I am 10 weeks and I worry all the time because I felt different a few weeks ago.. but I have not gotten sick once and my hunger is up and down... I have been told this is normal and everyone's different and everyone's symptoms are as well
Unless you have painful cramps and bleeding there is nothing to worry about I serious worry a lot like what if and stuff but I try to tell myself it's gonna be ok..
Relax it's okay :)
Try not to worry. When I was 17 weeks I didn't feel pregnant at all. No sleepiness, no nausea, nothing. But I am now 35 weeks with a healthy baby boy. You should be fine. Just relax. It will be alright you are about to enter your second trimester, the easiest pert of pregnancy, enjoy it.
