Trying to get pregnant...

My husband and I are trying to get pregnant, we have been trying for a month now, and I think I'll be getting AF this weekend but don't feel any signs of it. My appetite has grown a lot. And I feel moody. Took a pregnancy prevention today and still Not pregnant. Tho I feel "wet down there" more than I should. I don't ever remember feeling this way before getting AF. And my only child is 8 going to be 9, so it was a long time ago that I was pregnant. Any advice?? Thank you and sorry if it was a TMI... :/
