Haha betul betul! Timing is everything kan, kena intercourse around ovulation window baru ada chance untuk positive pregnancy test later. A few of us tried tracking ovulation dulu, some pakai apps, some beli those ovulation test strips, and memang helpful to know when to "try" haha. Once the sperm meets the egg during that fertile window, baru lah the pregnancy test line will show up after a few days. Patience is the hardest part actually, sebab kena tunggu hormone build up dulu before any test boleh detect!
