Oo, totally normal yan sa third trimester, mama! Ako rin dito, parang every 2-3 hours ako nagigising either dahil sa pressure ng baby sa bladder or hindi lang ako comfortable sa sleeping position kahit ilang pillows ang ginamit ko. A few of my mom friends say it's just your body preparing you na for the newborn phase, plus the hormones and physical discomfort lang talaga, pero if you're concerned na something else is off, check with your OB just to be safe, ha.
