Eh, dari segi medis takde pantang larang untuk pergi laut masa pregnant 10 weeks lah, tapi memang kena consider macam water safety, heat exposure, sama physical exertion yang boleh buat tired ke cramping. A few of my mum friends went swimming or beach time early pregnancy, but kena main cautious je, avoid the heat of midday, minum banyak air, dan jangan overdo things. Best thing is check with your gynae dulu especially since ni first baby you, dia boleh explain what's safe based on your pregnancy specifically.
