Ay alam ko yan! Rib pain sa third trimester is super common kasi lumalaki ang baby at nagsshift ang lahat, pero yung parang naiipit na feeling sa butt area, that could be sciatic nerve pain which a lot of us mommies experience din around this stage. I'd really suggest checking with your OB just to be sure, especially since it's combined, para peace of mind mo lang at ma-rule out kung may ibang reason, at they can give you proper stretches or positions na makakatulong talaga. A few of us tried pregnancy pillows and side-sleeping positioning, pero important talaga na ma-assess ng doctor mo directly para sa butt pain na yan!
