Hi mama! Please go see your doctor or go to emergency kaagad if the pain is sharp, won't go away, or may iba pang symptoms, side pain during pregnancy needs proper checking talaga, hindi dapat i-guess. One of my mum friends had something similar and turned out okay, pero better safe than sorry lang, especially kapag first time mo pa lang. Wishing you well, and please update us after you see the doctor! Take care po.
