Ay mama, ang sakit sa likod at balakang mo especially with low placenta is something you really need to check with your OB agad, hindi dapat i-risk yan, kasi some cases kailangan ng extra rest or monitoring pa lang talaga, pero dapat sya ang mag-assess sa iyo directly para sigurado. A few of us mums had similar worries at nag-worry din kami, pero ang bawat pregnancy talaga ay different, so better safe than sorry lagi ang approach natin dito!
