Sayang, this is important, please follow KK's instructions exactly, okay? Biasanya they'll tell you specific fasting time (usually overnight), so confirm with them esok pagi berapa kena datang and what you can/cannot consume. A few of us went through this, generally you won't be able to eat or drink anything (except maybe plain water, but check with KK first) from a certain time the night before. Stress a bit juga boleh affect results, so try to rest well tonight and don't overthink it. The test will give clearer picture of what's happening, so at least after this you'll know exactly what adjustments to make. Good luck, mama! You've got this.
