Eh sayang, sakit macam ditusuk dan rasa macam ada air tu, please call your doctor or go to the clinic today, ok? At 16 weeks, any sharp pain or that feeling needs to be checked out properly, tak boleh tunggu. Better safe than sorry, especially masa pregnant ni. Jangan worry sangat dulu, banyak benda boleh jadi, tapi kena clear dengan doctor. Minta hubby hantar ka clinic ye!
