Bakit masakit ang buto sa pwet ng buntis?

I’ve been experiencing masakit ang buto sa may pwet too, lalo na kapag mahaba ang upo ko. I think it’s caused by both the added weight and yung pagbabago sa posture mo. Yung ligaments sa pelvis kasi nagiging mas maluwag dahil sa relaxin hormone, which makes the joints more flexible but also painful sometimes. I read that this can also lead to pelvic girdle pain, kaya normal na may discomfort sa may pwet. I try to do some pregnancy-safe stretches and change positions frequently to help with the pain.
