Aiyooo, 4 minggu! Sayang, even kalau no bleeding, kalau ada any sudden pain or cramping after yang, better call your doctor or go to the clinic okay? Don't take chances at this stage, hormones and everything still very delicate. A few of us mums, kami selalu paranoid gak when hubby poke-poke area perut during early pregnancy, hehe. Jangan worry lah, tapi best check with your gynae just to be safe, dapat peace of mind.
