I am 27 been trying for my third child for 7 months

Me and my husband have been trying to concieve for 7 months. I came off of the IUD Mirena in march and than I tried the nuva ring. For a week than me and my husband talked it over and we want a third child. My cycles that I have been tracking starting from Aug-08-2009 to Sept, 08 2009 to Oct 13 2009 about 31 days except for oct I was sick and it came a little late. Now it is Nov6,2009 and I am about a week away from my cycle but I am having cramps in my left side and lots of white clear discharge that you normally get when you ovulate. But not strechy. I ovulated on the 28 of oct a little early accordind to the ovulation calander. I was just curious how long it takes to get concieve a baby.My first took two years my second took nine months. I am 27 and my husband is 28 . Could that be a problem?
