My fiancé and I have been trying to have a baby for almost two years now, is there any chance that we can't have kids?

Both of you should go to a doctor and get tested!

There is always that chance. Have you been to a fertility specialist? I would highly recommend that you both go and get checked out. They can give you the answers you need. Some couples just have a more difficult time getting pregnant. Hopefully you are one of those couples. Good luck, and go get checked out by a doctor!
