It is good to know that you believe in a planned pregnancy
. I would suggest that you undergo a baseline investigation to know if everything is Ok, as age is not the best predictor to know about ovarian reserve (number of eggs in ovaries) or semen factors (count and motility of sperms. If everything is ok, then yes, sure can wait for 2 more years. If any of the above is less than optimal, please do think of doing things sooner.
