A: These are all caused by getting fat during pregnancy. Exercise more, never go on a diet, and continue to pay attention to supplementing nutrition after delivery. You can buy some products to repair and eliminate stretch marks. During pregnancy, I used two sets of kangaroo mother's stretch marks to repair, occasionally rubbed its firming and slimming cream, and insisted on doing 20 sit-ups before going to bed. Slowly, the fat and stretch marks disappeared. You can try it my way!
