Prama you will def be fine going to KL. I travelled back from UK when I was 6 wks preg (we were relocating) and Ihave done a lot of travelling up to now for work. Give yourself more time to recover and take care but I am sure you are fine - I was told to stop flying at 34 wks latest. 2nd tri was 100%fine for me.
Enjoy it is the main thing!
