School or starting a family?

Claudia • Wife, Mom to baby Roman born 02.18.18💙
Hey guys, just wanted some of your opinions.  I've been with my fiancé for 6 years. We both graduated with diplomas in college and both have jobs.  However, I wanted to go back to school may 2017.  We get married January 14th 2017 and I've always wanted to start a family after I got married.   Can I try getting pregnant and go to school again, or should I just wait until school is over?  (School is about a year and 9 months). I'm currently in the health, wellness and fitness field but I've always wanted to be a medical massage therapist.   I just feel like after I graduate, I'll just be starting out and won't have enough time to work before leaving for maternity leave. Ugh
Let me know what you guys think.    
Thanks for reading!
