Does An Enlarged & Distended Uterus Indicate A Cyst?

i had a cyst 5 years ago on my right ovary.I had surgery and it was removed .Now i am married and trying to get pregnant but nothing is happening I noticed that my uterus is large and distended although no pain.I am worried abput it and know i have to go to the ob GYn .Is it possible this is another cyst?
