Hi Elyse,
I waited to see what others said before I posted a message. I basically agree with what others have said. Check out a fertility book, and learn about the signs in your body, which will tell you when you are fertile, and keep charts, after a couple of months, you will probably see a pattern emerging. Also, try not to get stressed, stress and worry does not help. Carry on life as you are, go out, don't stop drinking or whatever, just push it to the back of your mind. Most ladies fall pregnant when they give up hope and have an appointment to see a fertilty doctor, or it usually happens when you least expect it.
Getting stressed about it does not help.
Another good bit of advice that I was given, is to 'you know' (I'm trying to be polite here !)the 2 days before the day you ovulate, so that they little guys have a chance to swim up into the fallopian tubes and wait for the egg to appear. So, if ovulation day is day 14 of your cycle, then 'do it' on days 11, 12, 13. The more 'little guys' there are, the more chance you have of catching !
Hope this was of some use.
