Oh, yeah. It was really bad about a year ago - right after O I'd quickly get nauseous, and I could barely eat until AF showed up! Not nice. Doc said I must still be low on progesterone and upped my cream dose. Since I don't take that for a day or two afterwards, I'm not sure that's completely it, but I only get mildly queezy now for a day or so and back to normal luteal phase madness .
Are you still nursing? When I was nursing my daughter full time, I definitely got nauseous as my hormones were trying to return to pre-baby. But I'm barely nursing now and for the past 3 months the nausea seems to be my luteal phase.
