"I have to exercise, I have to swim, I have to do yoga or meditation, I have to get some sun, but not too much," says Ana, 37, who is seven months pregnant. "When you think you've done enough, you should start with perineal massage and also with the Pilates ball and, if possible, do manteo [pelvic massage with a scarf]." She has heard that there were many things she could do to ensure that the pregnancy and birth went well in a preparation that "never ends" and that "becomes an imperative demand," fueled by the feeling that she couldn't risk the pregnancy because she might not have more opportunities.
