Sayang, cramping in pregnancy boleh jadi normal, tapi since you're at 17 weeks, better check dengan doctor just to be sure, okay? Especially if the cramps are strong or ada bleeding, jangan tunda, pergi clinic atau hospital je. A few of my mum friends had similar stretching pains as baby grows, but honestly each pregnancy lain-lain, so your doc needs to see you properly. Drink plenty of water, rest when you can, tapi get it checked out ya? Take care of yourself
