Hi possum, I really don't know the answer to your question, but I think you should check with your GP to be sure. Gee, that makes it a bit tricky. My cycle lengths vary between 30 and 43 days but I don't get spotting. I know my OB wants me to take mine in the morning from the 2nd day of my period.

I have done one cycle of clomid and have 2 more rounds from my next period to take.

Wishing you all the best!!
