Ay, mama, I know that's scary! Please see your OB or go to the ER right away, abdominal pain during pregnancy without discharge still needs to be checked, kasi maraming reasons pa yan and your doctor needs to rule things out.
A few of us mums have been there, and honestly, hindi worth it mag-worry lang sa bahay, better to get peace of mind. Sabihin mo sa hubby or family mo na kailangan mo na bumiyahe ngayon. Wag magpahintay, okay? You and baby's safety come first.
