Anak, please see your doctor or go to the nearest clinic/hospital right away para masiguro na lahat ay okay, better safe than sorry, lalo na first time mo pa lang! Pregnancy pain can mean different things, and you really need a professional to check you properly. Hindi ako makakapayo ng specific advice dito, pero alam ko na marami sa amin na moms ang nag-alala din sa ganito sa early days, the important thing is magpaconsult agad. Keep me posted, ha? Thinking of you!
