Alah, I flew during that time dengan my second baby and was okay je, though I did feel extra bloated and uncomfortable! Most airlines allow flying up to 24 weeks, but best to call ahead and bawa your antenatal card with you, and try to book aisle seat para senang nak toilet. A few of my mum friends did the same thing without issues, just make sure you drink plenty of water, do some walks around the cabin, and don't sit too long, blood clots during pregnancy is a real thing to avoid, so movement is important! Kalau rasa anything feels off or you're bleeding, better check with your doctor before flying la.
