Wa'alaikumassalam sis! Ini memang boleh jadi scary, especially sebagai first-time mom, tapi free fluid luar ada kaitan dengan corpus luteum cyst atau inflammation yang biasa ja dalam early pregnancy, majority cases resolves on their own, okay. Best move is follow up with your OB/GYN closely untuk monitor, dia boleh explain lebih detail based on the amount and your scan findings, plus make sure everything inside the womb is progressing well. Jangan worry sangat muna, alot of mummies go through this and deliver perfectly healthy babies, the key is regular scans and staying close dengan doctor mu. You've got this, mama!
