Aww, I feel you mama! Five months pa lang kayo at okay pa rin ang nausea, honestly, a few of us still had it around that time, pero if it's making you really uncomfortable or you're having trouble keeping food down, better mention it sa OB mo next check-up kaya check lang din if may iba pang symptoms. Some of my mum friends said ginger tea, frequent small meals, at cold water helped, pero everybody's different talaga. Kaya mo yan!
