Morning sickness as a post period symptom???

Chloe • 27.
This is the second month in a row not that this has happened, so I'm wondering if this is normal.
A couple days after my period ends, I'll get terrible morning sickness.  Last month wasn't terrible, just was really nauseous and gagged a couple times.  Today, though, I woke up at 6am, gagged a couple times, went back to bed, woke up again at 8 and threw up spit.
Is this normal?
