Waalaikum assalam! Congratulations on the positive tests, tu memang exciting tapi tension jugak tunggu clarity kan? Honestly, with your Clearblue showing 2-3 weeks at 14/6 and doctor seeing a thickened uterus, sounds very likely pregnant, but you're still in that early window where ultrasound might not pick up the sac yet (happens between 5-6 weeks sometimes). A few of us mum friends went through this exact situation, tested positive tapi early ultrasound showed nothing, then 2 weeks later confirm ada baby! Just follow the doctor's timeline and go back after your missed period, that's usually when they can see it clearly. In the meantime, kalau symptoms macam kembung, tender breasts, or fatigue memang ada, try to jaga diet and rest sikit. The wait is killer, I know, but you'll have your answer soon!
