Ahhh I understand your worry, sis, dua line dah keluar, doctor confirmed pregnant, tapi small uterus on scan memang boleh buat orang nervous. A few of my mum friends pun ada rahim kecik masa awal pregnancy, and honestly it can be totally normal, sometimes it's just how some of us are built, or timing of the scan pun boleh affect the reading. The important thing is your doctor is monitoring you closely, so just follow up with all the scans and checkups dia suruh, and ask your doctor specifically what "kecik" means for your dates and your baby's growth, they'll track you closely to make sure everything progresses properly. Don't stress yourself too much lagi, tapi definitely jangan skip any appointments atau follow-up scans.
