Hi I only have a sec but wanted to reply. I found this on kellymom.con
"If you're eager to become pregnant first steps may include charting some cycles or reducing breastfeeding to evaluate your fertility status. If you are not ready to try to conceive, though, you may do well to take precautions since fertility reversals do occur.
Although there is no direct research, there is no obvious reason to believe that fertility treatments would harm the breast milk. To find out the latest on how a particular drug affects breastfeeding, turn to Thomas Hale, MD's Medications and Mothers' Milk. Clinical observations suggest that Clomid (Clomiphene) is compatible with breastfeeding.2 And there is no reason to expect that breastfeeding would affect your fertility treatment because the drugs will control your cycle.3"
