Aiyo, completely normal lah! At 25 weeks baby dah kuat tendang, so kena expect some sharp, stabbing sensations down there especially when dia active, it's just the pressure and movement hitting that sensitive area. Tapi kalau yang pain tu berlangsung lama, constant, or ada bleeding, better check dengan doctor just to be safe, okay? First pregnancy memang macam-macam rasa yang buat kita paranoid, hehe, tapi ni memang part of the journey. Congrats on your pregnancy!
