Alam ko, nakakaworry yan, lalo na kapag biglaan! Ang pubic bone pain sa pregnancy ay pretty common actually, siguro from the hormones na nag-loosen ng ligaments, or kung paano ka tumitigil/gumagalaw, pero since it just started at 13 weeks and nag-worry ka, mas better na i-mention mo sa OB mo next visit para ma-check niya properly. A few of us sa mom group namin nag-experience din ng ganyan, some were just the normal pregnancy aches, pero yun talaga ang mas peaceful feeling pag sinabi ng doctor na okay lang.
