Aihhh I feel you, the waiting game is the worst kan! Honestly, the most reliable way is to do a pregnancy test, either at home (get the digital ones, clearer) or go to the clinic for a blood test which is even more accurate. A few of us mums tried the home test and then confirm with the clinic just to be 100% sure because our emotions were all over the place jugak haha. Tapi if you're still very early, sometimes you can take the test too early and it shows negative when you're actually pregnant, so if your period is late, maybe wait a few more days or just go straight to the clinic lah, at least you'll know for sure and dapat proper guidance from the doctor. Hang in there sayang!
