Not many symptoms?

M
I'm 5 +2 and still don't have much nausea, maybe a 5 minute wave of it once a day or something but not much.  This is my second pregnancy and I feel like with my first I remember being way more nauseaus.  Besides that I'm exhausted and hungrier, no sore boobs and I definitely had that last time.    I'm worried that since I don't have the same symptoms as last time I'm more likely to miscarry.  Anyone else in the same boat?
