Oo naman, normal yan sa 30 weeks, maraming preggy friends ko ang nag-complain ng same thing, it's the weight of the baby plus the hormones loosening everything up na nakakasakit talaga sa pelvic area. But since it's quite early pa at it's bothering you, worth checking with your OB just to rule out anything else and para ma-relieve mo ng proper suggestions, maybe pelvic support or specific stretches na safe for you, kasi pag lumaki pa baby mo baka mas lumala pa yan, diba?
