I managed to get a cancellation appointment for Monday for the Consultant (supposed to be in January so this is great!). I've gone through treatment before (DS now 15mo) and first time round had 6 unsuccessful rounds of clomid (short luteal phase, poor thickening of lining and absent ovulation.) Then after first shot of IUI got my BFP. A Nurse who works there old me they have started using letrozole and that Consultant may recommend this. Should I give it a go or just go ahead on the waiting list for IUI (9 months.) I cannot go on waiting list if am on letrozole so it does delay things. I found the clomid scenario very stressful with months of no response but maybe letrozole would be different?
