Ohhh 5 weeks pa, congratulations! Honestly the feelings can be quite different each pregnancy, I remember with my second, rasa lain sikit dari first juga, maybe sebab body dah tau what's happening kot Cramping and sharp pains especially after eating memang boleh jadi normal dalam early pregnancy, but since your second pregnancy rasa berlainan dari yang first, better to check with your doctor cepat-cepat just to be safe and put your mind at ease, they can confirm everything's on track!
