Hey mama! At 5 months, ang baby mo ay nagsisimula na talaga ng maraming movements kaya very possible yan, basta walang bleeding at okay lahat ng ultrasound results mo, that's a good sign! A few of us first-time mums din nag-panic sa ganyan, pero it could be baby moving, uterine stretching, or ligament pain on that side, basta para ma-ease ang mind mo talaga, check with your OB na lang sa next visit or sooner kung mas uncomfortable ka, kasi sila na mag-confirm kung ano talaga yan.
