Nausea/vomiting/HG in more than one pregnancy

Holly
Pregnant with my first. Still vomiting, not nearly as bad as the beginning but I thought it would be over by now. I had a good stretch for about a week but it's creeping back. 
I'm wondering, did any of you suffer from a lot of nausea and vomiting in the first pregnancy but not the next pregnancies? Very curious!
