Perhaps you answered your question with "I want to get my masters' degree before..children" There are multiple variables; number of children, motivation for getting your grad degree, childcare plan, support system for your family, your personal dreams and vision for your life.
My wife has a grad degree and she choose to stay home with our three children. I have the chance to start a business at age 41. (my oldest is in Kindergarden) There is no right answer only questions that guide you towards the things you value most & what you are willing to do to get there.
Hope you find value in my reply
