Bun, Clomid does just that. It boosts your hormones but I don't know that you get a "better egg".

If you have a LP defect than clomid will likely help you. For that reason alone I think it's a good idea and as I said I used it to effectively lengthen my LP.
I had 4 rounds before I conceived this baby. It's not a magical cure and it will not decrease your overall miscarriage rate. It will decrease the liklihood of a chemical miscarriage caused by a short luteal phase though.

I am sorry if I have deflated you. Bun, the great thing is you are ovulating well - the clomid will give a boost to those hormones that will hopefully lengthen your LP - thus increasing your chance of conceiving.

I will pop back again later to post more - I have to go out...
