Alamak, 5 minggu tu memang boleh rasa macam-macam, tapi kalau denyutan dan cramp tu quite strong, better check with your doctor quickly ye, especially since it's in that specific area. A few of my mum friends yang pregnant also rasa benda pelik kat early weeks tapi they all went for a scan just to be sure, and honestly it puts your mind at ease. Jangan worry sgt dulu, tapi jangan delay doctor's appointment sebab they need to check if everything's progressing nicely dengan baby.
