Yes, that's called having an aura. Mine usually isn't nausea, although sometimes it is. Usually, I get sensitivity to light and weird lights flashing, and/or blind spots, so mine are more visual, but nausea is a pretty common one too. My aura happens about an hour to half an hour before the migraine though, but I have heard that it's different for everyone.
