No morning sickness...

I'm 6 weeks pregnant with some symptoms (exhausted, cramps) and at the beginning of the week I was super sick to my stomach and kept having to use the bathroom for 3 days straight, so I thought maybe that would be the type of morning sickness I got. But it has gone away and I occasionally feel a little nauseous (that feeling you get at the top of your chest/bottom of your throat) but that is it. I have read that somewhere between 50-90% of women get morning sickness and that women who get it are less likely to miscarry (I have had 1 miscarriage before). So anyways, I was just wondering if any of you still had not gotten morning sickness this early in your pregnancy?
