Inconsistent result

Hi mommies! Saya first time dapat double line after 1year and half ttc. Saya test 23/5 dapat double line tp kabur. Buat test lg sekali utk konfirmkan tp line makin kabur. Harini test lg negatif pulak. Ada sesiapa pernah alami macam ni? Confius saya pregnant ke tak ni ? Btw, last period 7/5 which is dah delayed for 9days, and period cuma 3 hari xmcm yg sbelum2 ni. Help me.
