I was on clomid two cycles for DS following a naturally conceived miscarriage.
When we started TTC this time I fell preg first cycle of clomid but miscarried again. It was probably the first successful round of clomid we fell preg with current bun. (I took a few doses following miscarriage but didn't have any effect on ovulating but once it did we were lucky to catch the egg.)

Good luck :-) I hope u get ur BFP soon!
