Ok, that's better!!

Is it possbile you O'd on CD15 (when you had the EWCM)?? I only say that because in your symptoms you've noted that your bb's have been tender and heavy since CD15... I know on my last cycle, FF had my O day on CD11 because I had a temp rise, but I knew that I hadn't O'd because my boobs hadn't gotten sore.

Your temp normally only drops once AF is ready to show up... IMO, I think you O'd on or around CD15-16 and are only 5DPO... that's just my opinion though...

So you don't have a clear idea of when you'r AF is due? Could you maybe go to the doctor and get a BT to see if you've O'd??

Sorry... I wasn't a great deal of help was I
