During the first trimester, some mom’s experience fatigue and nausea. This subsides anywhere from 12-16weeks. It is important to give your body the time to rest and relax. The baby needs an environment that is as stress free as possible. During this time, try not to push or over-exert yourself. If you are practicing yoga regularly, consider skipping ‘vinyasas’ and take childs pose several times during your practice.
