Mama, please go to your doctor or OB right away to get checked, ang sakit sa tiyan especially after birth ay hindi dapat i-ignore, kaya better safe than sorry! Alam ko nakakabahala, pero talagang kailangan mo ng professional check-up para malaman kung normal lang yan or may kailangan i-address. Could be maraming reasons, from normal healing pains to something that needs attention, pero doctor lang ang makakaalam for sure. Don't wait pa, mama; your health matters! Sending you love, and I hope it's nothing serious. Let us know how you go!
