Ay mama, constipation during pregnancy talaga ay common pero masakit na talaga puwitan mo, kailangan mo na talagang consult with your OB about using Bisacodyl or any suppository kasi may certain medications na safe lang sa certain trimesters, at gusto natin sigurado na okay lang sa baby mo. A few of us mums struggled with this din, at ang OB namin usually recommended natural remedies first like lots of water, fruits with fiber, at prenatal vitamins with docusate before jumping to stronger stuff, pero sa case mo na may pain na, definitely see your doctor na para safe at ma-relieve ka na agad. Sending you comfort soon, mama!
