bad nausea during pregnancy and recurring nausea post partum?

I'm nearly 4 months postpartum. During the majority of my pregnancy I threw up daily and had almost non stop nausea. That ended during the third trimester, but I have strong aversions to this day. There are only a few things I'll eat. Occasionally I'll still get terrible waves of nausea, but I don't throw up. Anyone else experiencing similar? Is this normal?
