Aaah congratulations on your pregnancy! Honestly boleh je berenang at 5 weeks, tapi you know la, better to check with your doctor first especially if you're worried, setiap pregnancy kan berbeza, and some mums have spotting or complications yang we don't know about yet. A few of us dalam circle aku siap berenang sampai 8-9 months, tapi tetap kena cleared by doctor dulu. Just make sure the water is clean, chlorinated pools are generally safer than beaches, and stop if you feel cramping or anything weird la. Congrats again!
