Oo normal yan sa first trimester, mama! Ang ligaments mo ay naghihintay na mag-stretch para sa baby, kaya minsan may mild cramping or tugging sensation around the sides, a few of us din naka-experience nito around 11 weeks. As long as walang heavy bleeding or parang labor pains, most likely yan lang yung round ligament pain, pero since nag-aalala ka, better to mention it sa OB mo next check-up para ma-confirm lang na all good.
