Uy, congrats sa pregnancy! But sis, kahit common ang stretching sensations during pregnancy, mas safe na i-check mo ito with your OB para sure lang, especially if sobrang sakit or may ibang symptoms like spotting or cramping. Better safe than sorry tayo, lalo na first time mo pa lang. A few of us moms had similar concerns and the doc just gave us peace of mind, so go na lang for your check-up! Keep me posted, okay?
