I am ttc2 and have been for a good year. No troubles with conceiving DS but I am now 40. My cycles have been very regular - 24/25 days but over Christmas I started spotting on CD18 after a much lighter and less painful period than usual, this went on for 6 days, stopped for about a week and started again 2 days ago. I am wondering where my normal periods have gone? I haven't had a pain free period for about 10/12 years and while it is nice not to have to break out the Nurofen it doesn't seem right. Has anyone else had experience of spotting/unusually light periods coming just a week apart?
