Oo, normal yan sa second trimester, mama! Ang ligaments mo ay nag-stretch at lumalaki ang baby, kaya common talaga ang mild cramping or soreness, parang pagsasakit lang ng muscles, di ba? Pero kung sobrang sakit, persistent, may spotting, or may ibang symptoms, please check with your OB agad para sure lang, lalo na first baby mo pa. A few of us moms experienced the same thing, pero mas napanatag kami after doctor confirmed lahat okay sa ultrasound. Take care, at wag mag-alala too much!
