Why do i feel nauseous especially upon waking im 5 weeks pregnant how can i stop nauseousness?

Very common: Nausea is the last common symptom of pregnancy. The good news is that it usually resolves after the first trimester (3 months). You can try munching on crackers (be careful with salt intake), and eat smaller meals more frequently over the day. Ginger ale or some type of ginger may be helpful. Hang in there. Hopefully, that will be the worst of it.
