OK. Let me start by saying that my cycles are more regular and reliable than Big Ben. They are 28 days in length and I bleed for 5 days. I am on CD 12 and I started spotting this morning. It started out as bright red and is more brown now. I need to wear a panty liner, but it's just spotting. I know, it's TMI, but I am so confused and worried that something is wrong. The only thing different about my cycle is that my period started a day late (29 day cycle) and ended one day early (4 day period). Also, I've been trying Robitussin to increase CM. Does anyone have any ideas? Nothing like this has ever happened to me before, so I can't help wondering if something is wrong. I should be ovulating, not bleeding!
