Clomid to my knowledge doesn't cause bleeding. I have been off and on it since 2007 and never had break thru bleeding. You might want to check with your obgyn office and see what they say :) Good luck and Baby dust to you both :) XOXO
Emmasjem- Hi, I'm not sure about the spotting but i just wanted to let you know that this month was my first month on clomid 50mg started on cd 3 to cd7....and my period ended that day as well (cd3)...I usually have 4 or 5 days of bleeding....so clomid may also have a hand in the spotting since you only had your period for 3 days as well.
