Hi M.~
Every pregnancy is different, I know mine were. I will tell you this, any doubts call the doctor. Don't wait to get all upset or worried about it, you need to hear your doc say everything is fine.
How old is your 1st child? Maybe you dont' recall feelign this way in your 2nd trimester? Is your first child a girl/boy and maybe these symptoms are different due to the gender? There are so many things that can trigger the different symptoms- have you been eating/activities any different?
3 days is a long time to be vomiting, even for a normal person- call the doctor for at least, if anything, reassurance so you won't be worrying. Good luck, and please let us know what happened. Take care. You are in my prayers :)
