Oo mama, totoo yan! Pelvic pain during pregnancy is SO real and honestly grabe talaga, a few of us mums talked about this and parang may isa na kami na literal na nahihrap maglakad by the third trimester kaya naiintindihan ko ang "collapse" feeling mo. The hormone relaxin is loosening everything up para makapag-expand ang pelvis for delivery, kaya talagang nahahawakan mo na parang fragile yung bones mo dito. Best thing is to check with your OB about this para ma-rule out pelvic girdle pain or something else, at pwede niya i-recommend din kung may safe stretches or support belt na makakatulong, walang dapat idulot na pain sa pregnancy, so it's worth getting checked out para ma-ease mo yan!
