Hindi po, hindi lang 36 months ang normal pregnancy period, usually 9 months lang or around 40 weeks from last menstrual period ang standard gestation period para sa healthy pregnancy!

A few of us moms din nag-panic dati with timelines kaya importante talaga ang regular check-ups para sa peace of mind.
