I have got me prescription of Clomid and just waiting for the

to come so I can start my first course. I was told not to BD for about 2 days before my CD12 scan, then they would tell me after the scan if it was ok or not. The nurse at my Clomid consultation told me that it is in case you produce too many follicles which in turn may mean a multiple pregnancy and risks to either mum or babies or both. Best to check with your clinic though.
