Alhamdulillah, congrats sis! Don't test lagi lah, if three different brands all showed +ve lines that fast and getting darker, that's legit positive, mahal brand ke cheap brand sama je the test works the same way, so sabar ja tunggu scan on Sunday to confirm everything! A few of us dalam group PCOS also tested multiple times sebab paranoid haha, but honestly once you see that line appear so quickly across different tests, you can be quite confident, now the hard part is just waiting for the scan to see that beautiful heartbeat! Fingers crossed for you, and InsyaAllah this is your time after trying so long.
