Thinking of taking clomid together with IUI to help conceive. We've tried cycles of unmedicated IUI with no success. I am 40 and DH is 46 and we both have 2 DCs each. We really really don't want twins and so had ruled out clomid as an option BUT, it seems that it's really all that is open to us unless we want to continue with unmedicated IUIs with have low success rates. Just wondering how many people took clomid and conceived twins. Dr said the risk if up to 20% which is really high.
