@DrDara, thank u so much doctor

During pregnancy at 30 weeks, the baby's position is still head up. Your 30-week fetus is floating comfortably in about 1½ pints of amniotic fluid. Back pain is a very common symptom of pregnancy especially at around 30 weeks and generally throughout your third trimester. Discomfort and intense lower back pain are quite common in pregnancy as your muscles and ligaments tire from the extra weight you are carrying.
