Yoga can be done safely throughout the first trimester of pregnancy, but only with the guidance of a certified yoga instructor who is familiar with your medical status. Yoga asanas should be done with caution and under the supervision of a yoga instructor because certain asanas and positions may limit blood supply to the uterus, resulting in sprains or muscle spasms. More information regarding early pregnancy yoga teacher training is available from Pratham Yoga.
