Aw normal lang yan, mama! Sa 6 months usually mas malakas na ang movements kaya mas napapansin mo, and yup, all that kicking and turning can press sa bladder mo kaya frequent urination, plus the nausea might just be pregnancy hormones doing their thing. A few of us mums experienced the same thing around that time, one friend said parang may partido inside haha! But since you're noticing a change from last month, best to mention it sa OB mo on your next visit para peace of mind lang, para ma-check na lahat okay sa baby and sa iyo.
