Siguro ligament pain yan, mama, ang round ligament pain is super common sa second trimester, pero pwede na rin mag-start sa early pregnancy, lalo na kung first time mom ka and your body is stretching pa lang. A few of us experienced yan around 11-12 weeks at medyo nakakatakot talaga, pero honestly best to check with your OB just to be sure, especially kung may bleeding or hindi lang dull ache, they can give you peace of mind at proper advice for your specific situation.
