Should women do Yoga during menses?
Mostly it's a matter of personal preference. Some women don't want to do yoga while have their period, many don't mind and continue to practice during menses. For women who do choose to practice, it is suggested that they avoid inverted poses, abdominal strengtheners, extended holding of any pose, or energizing breaths (kapalabhati). The issue is that these practices might interfere with the downward flow or cause discomfort.
Is it okay to practice Yoga while pregnant?
As with any form of exercise, it is okay to continue practicing yoga while you are pregnant as long as you were practicing before conception. Yoga is a great way to keep fit during pregnancy. In particular it can help strengthen the pelvic area, normalize thyroid functioning and blood pressure, and help keep you calm and relaxed -- all of which is good for the baby, too. In general, however, you want to avoid strain, compressing the belly or abdomen in closed twists and inverted postures, especially in the later stages. Taking prenatal yoga classes can help you learn how to practice safely and modify poses appropriately, as well create opportunities to build a supportive social network.
