First of all, before you start trying to get pregnant, I'd recommend seeing a gynecologist.
Getting a check-up of your reproductive health (a gyn exam, STD screening for you and your partner, etc.) before you start trying for a baby is just common sense.
And you'll need to have a working relationship with a gyn to provide medical care during your pregnancy.
Yesterday, you described symptoms which could indicate an infection, so you really need to get those checked out:
With most couples trying for a baby, pregnancy happens within the first year (generally, couples are not considered to have a fertility problem until they've been trying for a pregnancy for two years without success).
If you want to maximize your chances, then you can get into fertility awareness (charting your basal body temperature and monitoring your cervical mucus - it's not simple, so get a book) so that you know when you are most likely to be fertile.
And obviously, you also need to ensure that you are actually prepared (emotionally, financially, everything) to handle a pregnancy, support and care for a baby, and so on. Getting pregnant is just one small part of the deal.
