Hi Nicole, I have been ttc for 6-months and was thinking of trying AC next cycle if this one is not successful. After reading this thread I am convinced it is worth having a go. I had to laugh reading about people just starting AC and then looking at their tickers and seeing that they must have conceived in one or two cycles! I really hope this works for you, ttc for 18-months must be stressful, but there is a lot to be positive about when you read other's testimonies, so all the best. I'll keep an eye on this thread and hope to see your BFP soon.
