Tahniah dulu on your pregnancy! Rahim tebal tu completely normal in early pregnancy, that's actually a good sign sebab means your uterus is responding well to hormones, and the fact that doc already nampak kantung is really positive, jangan risau! A few of my mum friends had the same worry first time round and doc assured them it's nothing, just hormonal changes preparing your body; the important thing is everything looks progressing as it should be at 7 weeks. Just follow up with your doc at your next appointment and ask any questions yang buat you anxious, they can explain in detail and ease your mind, because at this stage usually they just want to monitor growth and heartbeat je. You got this, mama!
