Mine started at 5-6 weeks and has never gone away. (I'm 30 weeks now) Pray that you don't get it. Haha. It's horrible, and if you're lucky enough to avoid it then be happy. :)
with my first 3 i had no morning sickeness or nausea. with this one its terrible. so it just depends on the pregnancy
You might be lucky enough not to ever get morning sickness. I never did. I just had neausea from 6-14 weeks.
I guess everybody is different I havent had any yet.
Usually about 8+ weeks. It takes a while for HCG (the pregnancy hormone) to build up in your body and morning sickness is your response to it getting high.
Mine started around week four!
