Sayang, cramping dan pulling sensation awal pregnancy mmg boleh jadi normal, tapi sebab ni sensitive, kena check dengan doctor atau gynae asap untuk confirm semua okay with baby, especially at 8 weeks. A few of my mum friends had similar experience tapi turned out fine je, tapi some needed extra monitoring, so jangan ambil risk, go see your doctor first thing okay? Jangan worry dulu, just get checked out
