*meds not mess. Sorry about that.
If the mess you are talking about is clomid, my doctor told me to count any spotting before my cycle (the kind of spotting you know leads to a real flow) as day 1. But in saying that each doctor is different some say to wait to start counting until a real flow start some says to start counting at any sign of blood. I would suggest that you ask your doctor which he/she wants you to do. Hope this helps you, and good luck!
