Aww first time mommy jitters, gets! Light cramping is pretty common sa pregnancy, lalo na early on, pero since you're 12 weeks na, mas better na i-mention mo talaga sa OB mo next visit para peace of mind, especially if may spotting or if suddenly sobrang intense, okay? A few of us moms had the same worry, kaya don't hesitate to call your doctor's clinic if worried ka or kung parang off ang feeling mo, yan lang ang safest way talaga
