As your pregnancy progresses, your posture changes because your uterus is growing and pulls on your back muscles. Your pelvic joints also loosen. This may cause backache. To help prevent strain, wear low heeled supporting shoes. Your doctor may suggest a maternity girdle that gives support without binding.
Good posture is important in preventing backache.
Try not to lift heavy objects, particularly if there is someone around who can lift them for you. Here are several exercises that should help your back. Ask the nurse or someone at the clinic, to help you do the exercises if you are not sure you are doing them correctly. This squatting exercise helps avoid backstrain and strengthens muscles you will use in labor. Holding onto a heavy piece of furniture, squat down on your heels and allow your knees to spread apart.
