Ay, normal yan! At 25 weeks ang belly mo talaga, lalo na pag gabi, parang nag-tighten sila ng konti, yung Braxton Hicks contractions na yan, para parang practice lang ng body mo para sa labor. A few of us pregnant moms namin felt exactly the same, and one friend said parang may mild fever feeling din siya tuwing gabi kaya sinigurado niya na hydrated siya at hindi overworked. Best to mention it sa OB mo sa next check-up para peace of mind lang, lalo na kung may slight temp reading ka, pero usually harmless lang talaga yan. Keep taking it easy, mamsh, at mas maraming tubig!
