A brief, one-sided numbness in the morning that settles on its own isn't a typical part of morning sickness, but it's common in early pregnancy to feel this from a quick dip in blood pressure or from lying in one position overnight. It usually isn't something to worry about if it passes within minutes and nothing else is wrong.
Next Steps
Mention this to your obstetrician at your next visit, especially if it starts happening more often or lasts longer. If it ever comes with weakness, slurred speech or facial drooping, that needs same-day review, not a routine visit.
Health Tips
Go to the emergency room if the numbness doesn't go away, spreads, or affects one whole side of your face or body.
