My first pregnancy, it lasted week 8-13. I threw up about 5-6 times a day, basically first thing in the morning and any time I ate something. It was way better than my current situation, throwing up 1-2 times a day but being soooo nauseated I can barely eat. It started at 6 weeks and I am now 8 weeks in the thick of it.
