Hay naku, alam ko yan, round ligament pain yan most likely, super common sa 7 months kaya hindi ka nag-iisa! A few of us moms went through the same thing, parang nakakaattack sya out of nowhere talaga, especially pag biglang gumalaw or tumayo. Try na lang muna rest, warm compress, at bawas ang mabigat na activities, pero if ang sakit ay sobrang intense, hindi nawala, or may ibang symptoms, kailangan mo talaga i-check with your OB para ma-rule out ang iba at ma-ease your mind, better safe na!
