An undeniable effect you'll experience in your first trimester is nausea and fatigue. This relaxing meditation offers space to comfort these feelings of unease and is great to come back to again and again. Use a blend of visualization, Ujjayi breath, a body scan, and a mantra to calm your senses and thoughts, simply being present with your body and your baby. Please Note: Prenatal yoga is for those who have a low-risk pregnancy and have gotten the green light from a doctor or midwife to practice.
