Trying Not to Conceive

Shelby • Married Aug ’17—baby #1 March 2020
So my fiancé and I are getting married in August but we are both still in college so we aren't quite ready for a baby yet, probably won't be for the next year and a half to two years! I'm already on birth control pills(for managing my period--we are waiting until we get married), and am pretty good about taking them on time.
So if I am adamant about taking them exactly on time everyday should just being on the pills be enough birth control or should we use condoms when I'm about to/am ovulating? And any other advice would be great
Thanks!!
