I'm in the same position - Everyone says 'You shouldn't have babies young, go out and enjoy yourself'. I think going out clubbing etc is only fun to a certain extent then it gets repetative and not as much fun as it used to.
Both my friends who have had babies brought them in last week. [One was 3 days old and the other was almost 5 weeks old], and I could imagine what it would be like when I have a baby and that I would enjoy it - Obviously not all the time but it would all be worth it

Try not to worry, you've only been trying for about a month - you've got tons of time!!
