Uy, first, please confirm with your OB right away kung okay lang yung pain na yan, lalo na may placenta previa ka, important na masiguro mo.
Since naka-bedrest ka for a month, totally understandable na may discomfort lagi. A few of us moms with similar situations noticed na ang positioning at movement habit namin nag-trigger ng cramping din, so buti na sinigurado mo sa doctor kung pwede ka umupo for work. Your OB knows your condition best, so trust their guidance on what movements are safe for you right now. Hang in there, mama, alam ko mahirap ang bedrest pero it's all for your baby. Wishing you and your little one all the best!
