Congrats sa second baby, mama! Oo, normal lang yan sa pregnancy, lalo na ngayon na 11 weeks ka pa lang, ang hormones at hydration mo ay nag-aaffect sa urine frequency, so it varies talaga from day to day. With my first I was going crazy thinking something was wrong, pero with my second I realized kung kumain ako ng maraming salty food or mababa ang water intake ko, naturally less frequent ang pee, kaya make sure ka lang na hydrated ka talaga throughout the day, mama, at kung continuing pa rin ito or may ibang symptoms ka, better check with your OB para sa peace of mind lang!
