Honestly, normal lang yung slight cramping or pulling sensation sa belly during 10 weeks dahil lumalaki ang uterus mo, pero if it's sharp pain or may bleeding kasama, definitely konsultahan mo agad ang OB mo para sure, better safe than sorry talaga sa first trimester! A few of my mum friends nag-experience ng mild discomfort early on kaya alam ko it can be scary, pero importante talaga malaman kung anong type ng pain exactly so the doctor can check properly.
