Not everyone gets morning sickness...so don't stress, just enjoy the fact you don't have it right now. My boyfriends family keeps joking with me that I'm faking my pregnancy b/c I don't have sickness at 16 weeks, I guess every female in thier family has had it. But talking with my mom, only one of my aunts had morning sickness, and we have a lot of females in my family...so I guess I lucked out on that one.
Its normal. Just wait, my morning sickness hit at 6 weeks and I was miserable until 16 weeks! Everyone said 6 weeks was pretty early too. There is always a chance you wont get it but usually it won't start for a couple more weeks (:
