No, there is nothing wrong with you, at least not yet. Dr.'s don't even like to see you until you have been actively trying to conceive for at least 1 year, 6 months if you are over 35. It took me over one year to conceive my first daughter and then 2 years and three months and 2 miscarriages to conceive my twins (will the help of some wonderful Dr.s and IVF).

If you want a really good book to guide you in the right direction, I would get Taking Charge of Your Fertility. It really is a great book and will answer a lot of the questions you might have about trying to get pregnant. Good luck!
