You mentioned that you have been sick.. Did you happen to take any cold and flu tablets or antihistimene (sp?) I have heard that something in those kinds of medications can hinder the production of CM. I dont know how true this is but i have read it on a couple of websites..

Try not to stress about it too much. When i was on the BCP i always got heaps of EWCM around the time i should have ovulated. Yet as soon as i came off the pill i got none. Quite liteerally none for the whole 7 months before i got UTD. I just BD around the time that i thought i should o, but interstingly the last month (when i got pregnant) i used preseed and thats when it finally happened. I dont know if it had anything to do with it - but it was the only thing that we did differently!

Good luck huni - i hope that you get your BFP soon!!!!!!!
