Trying to Conceive but can't..

In August of last year I found out I was 5-6 weeks pregnant. At the beginning of September, I miscarried naturally, and I didn't have to get a d&c. My period was abnormal for a couple months. But it is on track now. My partner and I have been trying to conceive since the first of the year and it just isn't happening. I know it takes time and patients. But I am young and it should be a little bit easier shouldn't it? I just need some advice and help on what to do to try and conceive a child. Things to do and not to do while trying to conceive.. All advice and comments welcome.
