Hi KB
I know my clinic only allowed me to take clomid for three monthes, main reason is it can actually CAUSE infertity by effecting the endometrium and yes it messes with CM, there are no proven stats but there seems to be some concern between lengthy use and cervical cancers, dont want to freak you out so investigate before taking it on board, i know someone at a different clinic too me and they too were only allowed clomid for 3 cycles. I would be asking some serious questions as i think the disruption of the endotmerium is a big concern when your trying to fall pregnant, id definately want some answers ( and possibly a move to someone who is a little more switched on)or a reason to why they are keeping you on it for so long, maybe ask about puregon, as i started on it when i couldnt do clomid any more.Also your cycles should get sorted first (probably using the pill unfortuantely) before going on fertility treatment. The tests the fs do are check DH swimmers for count and motility, you both have to get some blood tests (transmittable diseases and rubella etc.) some will do a HSG where they squirt die up your tubes too check they are ok and most will do what they call a tracking cycle, where you go for LOTS of blood test almost everyday to check whats going on with your hormone levels and to see if and when your ovulating, this includes an ultrasound. I hope this helps, it is full on but worth it to get everything happening right. good luck
