whoop sorry Miss K forgot to say welcome to this thread, but sorry can't help re. AF being heavy as i'm just on my first cycle of clomid. however, it is my understanding that if you don't ovulate your AF is meant to be lighter than if you do. So if you then taek clomid and start to ovulate then AF can be much heavier.. its not so much related to the dose of clomid but rather at what particular dose you ovulate (thats if you are taking it to induce ovulation!) Hope this makes some sense!
