Ay mama, better check with your OB pa rin kasi bawat tao ang healing, especially since naraspa ka after delivery, yung wound needs to be fully healed muna bago mag-motor. Five months is usually okay na para sa marami, pero ang raspa mo might need more time depending kung gaano kalaki, kaya seryoso talaga na patingin mo sa doctor mo para sigurado na okay lang ang incision before riding. A few of us moms waited a bit longer kasi paranoid kami sa vibration ng motor, specially pag may scars pa. Make sure din na stable ka emotionally and physically, hindi lang physically healed, ask your OB kung safe na talaga for you specifically, mama!
