Family Planning and Higher Education for a woman

I am a single, 29 year old female. My boyfriend/fiance/partner of 10+ years died about a year ago. I don't know what I'm doing about all that yet.

I want to go back to school. I think I have a very good chance at getting into a very good graduate computer science program. Due to cost, the fact I need to work full-time and giving myself the best chances for success, I will be doing this at a very slow, part-time pace.

I have been out of school for a while. You don't really need a degree in IT and I hadn't really considered going back because it didn't seem manageable or practical with the rest of my life. But... now that life is gone, it's cool because it has to be, and I would have never even dared to dreamed about being able to enroll in this graduate program before.

I don't necessarily care if I have a family and/or kids but I'm fairly positive it will not happen on accident. To me, being with someone or married does not automatically mean having kids, either. For the sake of the question, when I am ready, I feel it will be very logistically easy for me to date again.

From your experience... assuming I perform well with both work and school... what are the chances that I actually finish my masters? What have you seen happen to woman normally in this situation? Do they finish or do they stop for family (or maybe both somehow)?

I know a lot goes of consideration and luck go into these kinds of decisions but what typically ends up happening?
