Morning Sickness and other symptoms

C
I had nausea since 5 weeks and vomiting started at around 6 weeks.  The non-stop vomiting lasted less than a week, and turned into vomiting around 5 times a day.  Now I am 8 weeks and I usually vomit after brushing my teeth (within 10 min).  My nausea is off and on and that's pretty much it.  My boobs are hardly sore, but I am so tired all the time.  Does this seem normal to you? Or should I be concerned that my symptoms are decreasing this fast.  I have a doctors appt next week and I'm a bit nervous.  Has anyone else experienced this at around 8/9weeks?
On the otherhand,  this pregnancy has been rough- I got sick with a severe cold during week 5 and still have a cough from it.  My tooth got infected so now I have to get it pulled in a couple days. What a whirlwind of emotions!!
