Anak, please see your doctor or OB right away para ma-check properly, lower abdominal pain in pregnancy needs medical eyes on it, okay? Hindi dapat i-ignore kahit konti lang, lalo na ngayon pa lang kayo sa early weeks. A few of my mum friends nag-experience din ng cramping early on, pero ang point is kailangan talaga ng professional check para malaman kung normal lang or may something na kailangan i-address. Better safe than sorry with pregnancy concerns, diba? Go na to your clinic or hospital kung available, they'll give you peace of mind kaagad.
