Changes in the Mother

Changes in the Mother

Backaches ∞As the baby continues to gain weight, pregnancy

hormones relax the joints between the bones in your pelvic area. These changes can be tough on your back.

Shortness of Breath∞You might get winded easily as your uterus

expands beneath your diaphragm, the muscle just below your lungs

Heartburn ∞During the third trimester, the growing uterus

might push your stomach out of its normal position= heartburn

Frequent Urination∞As the baby moves deeper into

your pelvis, you'll feel more pressure on your bladder

∞This extra pressure might also cause you to leak urine — especially when you laugh, cough or sneeze
