Sickness and eating

Donna
Blerghhhhh!
I'm 6 weeks tomorrow and all day I've felt
Sick but not been sick. The only thing to stop the sick feeling is eating which is so weird. 
Anyone else feel this that early? 
I've had 3 previous miscarriages and my last went to 17 weeks and I don't remember feeling like this at all last time 😷
Anyone any tips??
