14 weeks 6 days

Eh, jangan worry too much la, at 15 weeks, it's really normal for some areas of your belly to feel harder than others, especially if you've got kidney issues, sebab the uterus is still quite small and high up, so what you're feeling might just be that area or even your muscles tensing. Tapi since you mention you have kidney concerns, definitely check with your doctor about this just to be safe and set your mind at ease, one of my mum friends also had similar worries during her first pregnancy and doc said everything was fine, tapi better to confirm kan, especially with your medical history. First pregnancy memang scary sikit, but your doctor will know what's normal for your body exactly. Jangan stress-stress, baby can feel it, talk to your gynae at your next appointment, okay?
